ISO/IEC 10179:1996 Document Style Semantics and Specification Language was complete as of January 11, 1996. A related style language which uses DSSSL constructs is the Extensible Style Language (XSL). DSSSL is maintained by ISO/IEC JTC1/SC34 (Document Description and Processing Languages), Working Group 2 -- Information Presentation. The Convener for ISO/IEC JTC 1 SC 34 WG 02 is Dr. Yushi Komachi. WG2 "is responsible for producing standards for languages and resources for the description and processing of compounds and hypermedia documents, including: (1) Document processing architecture and formatting for logical documents (2) Multilingual font information interchange and related services (3) Final-form document architecture and page information interchange (4) APIs for the above document processings."

- HTML Help Version of the DSSSL Standard - DSSSLHELP, from Norman Walsh. October 27, 1998. "This HTML version of the DSSSL Specification is available in three flavors: (1) html.zip contains a "plain" HTML version [local archive copy]; (2) htmlhelp.zip contains a compiled HTML Help version [local archive copy]; (3) helpsrc.zip contains the sources for the HTML Help version [local archive copy]. HTML Help is the successor to Microsoft WinHelp. It is distributed with Internet Explorer 4.0 and more recent applications. The advantages of the compiled HTML Help version are an index and full text searching. It is supposed to be possible to support some or all of these features in other browsers using ActiveX or Java extensions, but I've never tried. It's also supposed to be possible to serve HTML Help over the web. Download the HTML Help sources is if you want try. In addition, you'll need (at least) the HTML Help for Authoring distribution.

['Although a forerunner to CSS and XSLT, DSSSL can still be used today with XML to create RTF, HTML, and other formats. Didier Martin show us how.'] "I'll talk about a grove processing and styling language, DSSSL (pronounced 'deesel'). DSSSL stands for Document Style Semantics and Specifications Language. Like groves, DSSSL is another technology with its roots in SGML, and sometimes suffers from bad press in the XML world. In fact, as you'll notice after reading this article, a DSSSL style sheet can be as simple to read and understand as a CSS style sheet. Both are rule-based languages, as indeed is XSLT. DSSSL is mainly intended for processing SGML documents but, since XML 1.0 documents are also SGML documents, they can be processed by a DSSSL engine. The OpenJade DSSSL implementation can be used to style DTD-less well-formed XML documents, as you would with CSS or XSLT. For those of you who use XSLT, you'll find DSSSL has some familiar processing concepts..."

'The tutorial does not presuppose a basic knowledge of Scheme.' "DSSSL is the Document Style Semantics and Specification Language and is meant to work with SGML, the Standard Generalized Markup Language. DSSSL is an international standard for associating processing with SGML documents. As you know, SGML itself is intended to allow the complete separation of the content of a document (text, structure, links), from the processing to be associated with it (usually formatting). So where a Word for Windows, Tex, or even LaTeX document would describe what a document looks like (in other words how a printer should 'process' it), SGML documents would only describe the structure. Using DSSSL you can describe the processing of documents in a standard way. Since the two most common forms of document processing are formatting and transformation, DSSSL standardised these two processes first. Others may follow as they are needed. . ." [local archive copy]

[October 20, 1999] On behalf of the OpenJade Development Team, Matthias Clasen has announced the Version 1.3 release of OpenJade. "OpenJade is the DSSSL user community's open source implementation of DSSSL, Document Style Semantics and Specification Language, an ISO standard for rendering SGML and XML documents. OpenJade is based on James Clark's widely used Jade. OpenJade 1.3 is the second OpenJade release. See below for a list of new features compared to OpenJade 1.2.2. You can download OpenJade from http://jade-cvs.avionitek.com. For more information, see the DSSSL/OpenJade home page at http://www.netfolder.com/DSSSL." Clasen also noted in connection with this 1.3 release: "you will notice that we don't provide a binary package for Win32. That is because we currently lack the necessary man-power/systems to do any testing/building on Win32 platforms. So if you are a Win32 jade/OpenJade user with access to MSVC and want to see OpenJade run well on Win32 in the future, please consider helping us by testing/building OpenJade-1.3 and/or the current CVS sources on Win32 platforms." Changes in version 1.3 are listed in the announcement. Note in particular: "(1) The SGML backend will not emit linebreaks when used as -t sgml-raw; (2) Jade can bind variables to arbitrary values on the command line; (3) The prlabs1 module of the SGML property set is supported; (4) Style sheet extensions .dsl lists all known external procedures ready for easy inclusion as an external-specification..."
[August 27, 1999] OpenJade Development Team Releases OpenJade 1.3pre1 (Beta). A recent posting from Avi Kivity and the OpenJade Development Team announced the release of OpenJade 1.3pre1 (Beta). "OpenJade is the DSSSL user community's open source implementation of DSSSL, Document Style Semantics and Specification Language, an ISO standard for rendering SGML and XML documents. OpenJade is based on James Clark's widely used Jade. OpenJade 1.3pre1 is a more complete implementation of the DSSSL standard, and introduces many new features, including (1) Implementation of most standard procesures; (2) Support for char-repertoire and related declarations; (3) Language support (including language-dependent procedures); (4) Standard color spaces are supported; (5) Special-query-expressions are recognized; (5) force! for inherited characteristics; (6) Character properties; (7) SGML architecture support extension; (8) The prlgabs1 SGML property set module is supported; (9) Binding of values to variables on the command line. You can download OpenJade from http://jade-cvs.avionitek.com. See the file jadedoc/jade.htm, included with the distribution, for building and installation instructions. For more information, see the DSSSL/OpenJade Home Page.
[June 09, 1999] [See preceding] Didier PH Martin posted an announcement concerning a new collection of Web pages for the DSSSL language. "You'll find useful references, articles, news and software all about DSSSL. This is the site in construction for the DSSSL user group. Avi Kivity already organized the source code on a CVS server. Ralph Ferris is busy working on the next Hybrick browser plug-in. I am busy working on the SGML/XML kit version 2 that will also include the Omnimark language in addition to OpenJade. Hopefully, if Keith work is enough advanced, the kit will offer an alternative to Microsoft's XSL engine. I am also slowly but surely documenting the OpenJade code (a long and hard job). I think that we'll soon be ready to integrate the OpenJade code developed by some of you for the next OpenJade release." The OpenJade source code, now maintained by the user group members, is available in a CVS repository. Note that the new DSSSL Web site and the 'OpenJade' effort have emerged in the context of a wider conversation about Jade/DSSSL held on the (Mulberry Technologies) DSSSList forum; see the May/June 1999 threads with subjects "Jade Maintenance," "Jade/DSSSL future," and "More on the Future of DSSSL." From one of the key postings by James Clark, maintainer of Jade - an implementation of the DSSSL style language: "My general feeling is that just as the future is XML not SGML, so the future is also XSL not DSSSL. When XSLT and XSL are done, there will (I hope) be nothing you can do in DSSSL that you can't do with XSL(T). DSSSL has not achieved widespread acceptance, and of course that's disappointing to all of us involved in DSSSL. But I think we have to face up to the fact that the main reason it has failed to achieve acceptance is not because of lack of promotion or explanation or marketing (although that has probably been a factor), but because of real useability problems in the language itself. XSL started off as a collaboration between DSSSLers and Microsoft to create a new syntax for the DSSSL style language that would be easier to use and could achieve wide acceptance. It hasn't quite turned out like that. On the XSL flow objects side, politics and market realities have necessitated building DSSSL functionality on top of CSS formatting objects/properties rather than starting with the DSSSL flow objects. On the XSLT side, as we've continued to work on the language we've found many ways to improve it, and the language has evolved substantially from DSSSL; however it's still very much the same approach to transformation as
jade -t sgml. There are big advantages to being in the mainstream, and XSLT looks set to become a mainstream technology. It's attracted the support of some of the biggest players out there -- Microsoft, Oracle, IBM, Sun, Lotus, Adobe . . ."

The DSSSL Documentation Project is "a collaborative effort by DSSSL users to write and disseminate documentation on all aspects of DSSSL for the purposes of: (1) introducing DSSSL to new users; (2) education for both new and experienced users; (3) assistance for people using DSSSL. The project draws on the combined experience of present users of DSSSL, principally those subscribed to the DSSSList mailing list, which also hosts the discussion between project participants."
- [November 09, 1998] G. Ken Holman (Crane Softwrights Ltd.) posted a description of a 'literate DSSSL stylesheet environment' package that has been using for a while to write a DSSSL script and its associated documentation in a single file. This tool is available for download. Description: "CSLDSSSL is an Annotatable DSSSL Stylesheet document model, where the annotations and documentation are captured in rich element structure, interspersed with the actual DSSSL code recognized by the DSSSL engine in the architectural instance of the stylesheet. The environment produces both HTML and printed documentation of the rich markup. . . The Annotatable DSSSL Stylesheet document model CSLDSSSL.DTD is rich with element content that contains parts, sub-parts, cross-references, and other constructs in addition to raw DSSSL code. The supporting documentation DSSSL stylesheet CSLDSSSL.SGM renders the rich embedded markup into documentation in three formats: print semantics, HTML markup, and distilled DSSSL code."

- [December 02, 1999] DSSSLprint Version 1.0 Available for Review. Fumihito Matsumoto (Next Solution) recently announced the beta/demo release of DSSSLprint Version 1.0. DSSSLprint 1.0 is an SGML/XML formatter, and its output formats are PostScript and PDF. The utility converts an SGML/XML document into PostScript or PDF by following the layout, style and pagination descriptions in a DSSSL (Document Style Semantics and Specification Language) script conforming to the International Standard (ISO/IEC 10179:1996). The demo/evaluation version of DSSSLprint1.0 is available for Sun Solaris 2.4 or above. A layout sample created by DSSSLprint1.0 is on Next Solution's web site. "DSSSLprint implements the DSSSL formatting language. By writing a style script that specifies how to format the structures found in an SGML document, you can format and print out on any PostScript Level II printer any document that conforms to the expected hierarchy. Furthermore, by creating other scripts, you can create other presentation styles for the same set of documents. The documents themselves are not altered in any way and once the script is created, the formatting process is automatic and independent of the content of any single document instance. DSSSLprint transforms the document straight into PostScript or PDF code, so there are no problems with intermediate files or programs like TeX or LaTeX. Features: (1) Layout results can be previewed on the display before printing on film or paper; (2) All PostScript Level II printers supported; (3) Supports TIFF, EPSF, JPEG and CGM graphic images referenced in the SGML/XML file; (4) DSSSLprint can be easily invoked from a GUI."
- [July 20, 1999] DSC Version 2.0 Released with DSSSL Transformation Language. In response to popular demand, Henry S. Thompson has announced the "long-delayed release of dsc-2.0, with support for the DSSSL transformation language in addition to dsc's DSSSL checking and debugging features." This 2.0 release had been "languishing in a not-quite-well-packaged state for over a year. . ." On DSC: "This tool, which embeds a full R4RS Scheme interpreter in James Clark's SP parser, is designed both to provide an online syntax checker for all DSSSL expression, style and transformation language programs, and to serve as a preprocessor for any Scheme-embedded DSSSL implementation. Virtually the entire language as specified in chapters 8 through 12 of the standard is checked for syntactic correctness, and a virtually complete implementation of the core expression language is included, as is the first-ever (as far as I know) implementation of the DSSSL transformation language. . . DSC implements the full semantics of the DSSSL standard regarding specification files, composing a specification body from one or more files conforming to the DSSSL architectural form, then mapping from the specification body (i.e., sequences of expression language forms) to a reordered normalised form thereof and loading the result into a Scheme interpreter with access to a document source grove. Comprehensive and detailed error messages, based on a large database of information about the calling sequences for all specification language functions and forms are logged to stderr, together with (optionally) information about feature usage. The semantics of the style language is not implemented, but the query and transformation languages are implemented, as is the core expression language, together with a number of optional compenents, with two exceptions: only 8-bit characters with single-character names are supported, and the functions
`time->string'are not implemented."
- [October 28, 1997] Announcement from Henry S. Thompson for the release of an alpha version of xslj, a Jade-compatible XSL-to-DSSSL translator. "XSLJ is a virtually complete implementation of XSL by way of translation into extended DSSSL, as supported by the latest test release of James Clark's DSSSL engine Jade. XSLJ translates valid XSL style sheets into valid extended DSSSL style sheets, which can then be used to render XML documents using Jade. Virtually all of XSL as described in the W3C document 'A Proposal for XSL' is supported, although some minor modifications have been necessitated by the exigencies of implementation, all of which are described in detail in material contained in the release. . ." XSLJ development was supported by the UK Economic and Social Research Council via their support for HCRC and by a grant from Microsoft. See the University of Edinburgh Web site for details: http://www.ltg.ed.ac.uk/~ht/xslj.html
- [February 15, 1999] Ralph E. Ferris (Fujitsu Software Corporation) posted an update on the HyBrick V0.80 support for XLink and XPointer. HyBrick is an advanced SGML/XML browser developed by Fujitsu Laboratories, the research arm of Fujitsu. HyBrick is based on an architecture that supports advanced linking and formatting capabilities. HyBrick includes a DSSSL renderer and XLink/XPointer engine running on top of James Clark's SP and Jade. It supports "both valid and well-formed XML documents, XLink and XPointer, SGML (ISO 8879), DSSSL (ISO 10179) online specification, printing and print previewing based on DSSSL stylesheets." To make the point [about HyBrick XLink/XPointer support, Ralph has] put some files with XLink/XPointer declarations in them up on the HyBrick Web site at http://www.fsc.fujitsu.com/hybrick/. These files are intended to be accessed over the Web. If your network access environment allows you to though, you can see XLink and XPointer at work over the Web by downloading HyBrick and pointing it at: http://www.fsc.fujitsu.com/hybrick/hubdoc-1.xml . . ." [see the posting for caveats and full details.] HyBrick Version 0.8 with XLink/XPointer support is now available for download.
- [February 16, 1999] Didier PH Martin posted an announcement for a new version of the DSSSL XML/SGML kit (for IE 4.x and IE 5.x).

See the text of the announcement for a list of changes in this release.
- [July 29, 1999] Braille Formatter - Braifo Version 0.0.1. Peter Nilsson has posted an announcement for the availability of Braifo version 0.0.1. Documents describing Braifo, as well as the source code, are available from the author's web site. Braifo, the Braille Formatter, "is a braille formatter and translator implementing a subset of the flow object classes defined by the DSSSL style language. The formatter has basic support for the following DSSSL flow objects: [sequence, simple-page-sequence, paragraph, character]. The development platform for Braifo is Debian GNU/Linux, but it is planned to run on as many platforms as possible (including Unix variants, DOS and Windows)." For additional details, see the Braifo home page.
- [June 09, 1999] Peter Nilsson posted an announcement to the DSSSList for the availablity of 'Braifo - A Braille Formatter'. "Braifo is a braille formatter that will generate braille out of an SGML/XML document. Currently it supports DSSSL using (OPEN)Jade. I am planning to also support XSL in the future, when the XSL spec gets more ready. Braifo will convert documents written in SGML into braille as specified in a style sheet. Braifo will support some, but not all of the featueres that are optional in the style language. It will also not support some required features of DSSSL, such as font characteristics, the external-graphic flow object class, etc. The page feature of DSSSL will be supported. This allows for generated headers and page footnotes. Neither of the multi-column, nor nested-column-set features will be supported. The bidi and vertical features also won't be available. The style sheet language is DSSSL, with some modifications to support braille. The development platform for Braifo is Debian GNU/Linux, but it is planned to run on as many platforms as possible (including Unix variants, DOS and Windows)."
- [May 02, 1998] Announcement from G. Ken Holman (Crane Softwrights Ltd.) for the public availability of an SGML/DSSSL Presentation Development Application. It is an SGML application for frame-based presentation slide-shows with DSSSL scripts for the rendering of the slides to HTML and RTF final forms. This shareware application may be used with James Clark's JADE DSSSL Engine "to create slide-show presentations and associated paper handouts" from SGML source documents. The tool is "based on an SGML document model (DTD) and uses two DSSSL stylesheet scripts to render the structured presentation in both HTML and RTF." See the Crane Softwrights shareware library for details.
- [July 20, 1999] Work in progress: Pomade: Poor Man's DSSSL Environment. "Pomade does the following things that are not difficult but tiresome for an experienced Jade user: 1) It lets you add application specific catalog files to those defined in SGML_CATALOG_FILES. In addition, you may specify which directories are to be searched for files whose SYSTEM identifiers do not contain a fully qualified path name. 2) It builds a top level DSSSL script that does not only invoke your main script responsible for the actual work, but also contains your current configuration choices (fonts, margins etc.) 3) If instructed to do so, it builds a temporary catalog file that maps PUBLIC identifiers used in the DTD or in a DSSSL script to SYSTEM identifiers reflecting your current choices. It also makes sure that this catalog file overrides the other catalog files. 4) It builds a Jade call with all necessary parameters for the output format(s) of your choice."

- New work [May 1997] on 'enhancements to DSSSL (ISO/IEC 10179:1996) for use on the Web.' James Clark has begun to identify further requirements for the use of DSSSL on the Web, and to describe enhancements that could be standardized within the ISO effort, or alternatively, "standardized by some other organization using the extension mechanisms provided in DSSSL." The new work may be considered part of the larger dsssl-o (DSSSL Online) effort -- identifying facilities that need to be added. Issues currently identified include CSS1 formatting, linking, Non-SGML packaging, Implementation simplifications, Inserting Objects, Java Applets, Forms, Scripting, Math, and Miscellaneous. The issues are sketched in a document entitled DSSSL WWW Enhancements; [mirror copy, May 23 1997].

- [November 14, 1997] Announcement from Norman Walsh for the "reorganization of the Modular DocBook DSSSL Stylesheets (both print and HTML). . . also some productive things. Please try them and report back. The changes between 0.93 and 0.94 are so extensive that it would be difficult to document them in detail. All of the files in this distribution have been updated to have a version number of 0.94. My primary goal in making these changes was to build a common library of code for both the print and HTML stylesheets. To achieve this goal, a great deal of code was moved around and reorganized." See: http://www.berkshire.net/~norm/dsssl/.
- [January 08, 1998] Announcement for the public release of Modular DocBook Stylesheets version 1.01, from Norman Walsh.

- Sample DSSSL stylesheet for HTML 3.2 print output, November 17, 1996. Using a DSSSL engine such as James Clark's Jade, this DSSSL stylesheet may be used to generate customized print views of HTML 3.2 documents (via RTFm TeX, etc.). The stylesheet has been designed for easy modification, and tutorial instructions show how the output can be modified (including customizations based upon a modified DTD). Although the stylesheet is lacking support for a few extended HTML features, it supports "features missing from HTML 3.2 such as headers, footers, optional autonumbering of heads and table captions, automatic TOC (Table of Contents) generation, and the correct and completely extensible interpretation of named units in size and length attributes. The DSSSL stylesheet was created by Jon Bosak of Sun Microsystems, with assistance from Anders Berglund (EBT) and from James Clark. The distribution of the stylesheet includes the HTML 3.2 DTD, the DSSSL stylesheet, ISO Latin-1 entities, and an appropriate CATALOG. It also includes a thought-provoking article by Jon Bosak, "SGML, Java, and the future of the Web" in HTML format ([mirror copy] ).

- [Perhaps partially dated information: DSSSL (Document Style Semantics and Specification Language) is under ISO Project JTC220.127.116.11.1. The second DIS version of DSSSL (ISO/IEC DIS 10179.2) was being reviewed (late 1994) for approval as an IS. Voting may (have) close(d) on 1994-12-25 or 1995-01-25. The draft version as of early 1995 is available through the normal distribution channels for a DIS, but is also available in PostScript or PDF format (partially in SGML as well) at a number of Internet locations. There is a special working group preparing a feature list for a DSSSL subset (DSSSL Lite), to be implemented as a means of supporting electronic style sheets for "HTML" documents.
