The quasi-final version of the stylesheet is available at
which contains the stylesheet and two HTML test files, after
1997-10-25T04:00:00Z (midnight tonight EDT).
;; DSSSL stylesheet for HTML 4.0 (97-09-17 draft) tables
;; Created for the W3C XML WG by Christopher R. Maden of O'Reilly and
;; Associates (firstname.lastname@example.org).
;; The cellpadding attribute needs to be handled by cell contents.
An example is provided:
;; The construction rule for P should be deleted when this is included
;; in the context of a full HTML stylesheet; it is present only to
;; handle content of sample tables and to give an example of
;; handling cellpadding.
This stylesheet is only intended to handle table elements.
;; This does not handle the SPAN attribute on the COL element, as Jade
;; appears to crash on n-columns-spanned: on a table-column.
James, if you download the aforementioned zip and uncomment the
n-columns-spanned section of html40.dsl, you should see the crashing
bug. With Jade 1.0 on Solaris 2.4, a seg fault happens as soon as
<col span="2"> is reached.
;; Assumes only LTR content and single TBODYs.
I'll probably add this at some point. If you actually need it, ask,
and it'll happen sooner.
;; Assumes that specifications are in pixels, and can be converted to
;; points at one point per pixel.
The reason for this is that <TABLE WIDTH="50%"> means that the table
should be 50% of the current width. I'm not sure how to determine
that. The HTML 3.2 stylesheet modified by Nigel Software AG relies on
a variable that is also used to create the simple-page-sequence; does
anyone know how to determine the currently available width? If that's
known, than I can figure out the table width and then the width of
columns that use percentages.
;; WIDTH and HEIGHT set directly on table cells is not supported.
This is a kind of gross HTML practice, and DSSSL doesn't lend itself
well to it.
A note of caution: test2.rtf contains background-color tests. It has
three 256-color tables, which hang Word 97 on a 32 MB PC. Use at your
own risk. (It will open the file so you can see the 16-color table,
but don't expect to do anything other than Ctrl-Alt-Del after opening
You'll need some ISO/IEC 10179 procedures that aren't implemented in
Jade. If you don't already have them, get
