   This DTD has been developed in order to validate XSL FO documents 
   conformant to XSL WD of October 18, 2000. The namespace prefix is 
   
     xmlns:fo="http://www.w3.org/1999/XSL/Format".

   This DTD also makes provision for few extensions to XSL WD, put 
   into a separate namespace:

<!-- *******************************************************************

This DTD was written in mind to validate testcases for the new XSL FO 
draft. Therefore, it is restrictive with respect to the WD: some rare 
XSL FO features have been dropped in order to validate others more 
reliably. Unless a document intentionally uses some of the functionality 
listed below in the intruductory notes, it shall be conformant to this 
DTD in order to be a valid XSL FO document. 

INTRODUCTORY NOTES

1. As compared to the draft of 1999-04-21, the current one is hard
to validate by a DTD: attributes are now universally inheritable due
to the adoption of the 'inherit' value from CSS2; and even for the 
content model, presence of universal wrappers like fo:wrapper makes 
it impossible to trace a neat distinction between inline-level and 
block-level content. Therefore, this version of the DTD cannot reliably
detect inconsistencies in attribute sets: real checks are performed 
only for empty inline elements and top-level elements (fo:layout-master-set 
and its descendants). 

2. In order for the validation to work properly, you should first
clean out all the contents of fo:instream-foreign-object and all 
non-FO elements from fo:declarations. It is expected that, prior
to validation, a filtering script should be run on the FO document. 

DEVIATIONS FROM THE DRAFT

1. Content model for <fo:layout-master-set> is made more strict:
at least one fo:simple-page-master should be present. (I think this 
is more like a correction to the WD, rather than a deviation from it).

2. In the WD, page and region-body margins may be expressed in terms
of space-*. This does not make any sense, as far as no stacked 
constraint may occur. For this reason, I have disabled spaces
in this context, leaving only plain old CSS margins.

3. Attributes of elements inside fo:layout-master-set may have a value 
of 'inherit'. However, I have disabled the occurrence of such attributes
on parent elements: inheriting them buys us little in terms of 
conciseness, but is error-prone in the initial phase.

4. Table-omit-{header|footer}-at-break is added a value of 'inherit',
to align it with the rest of table attributes. (If table-layout may have
it, why these two should not?)

5. Text-align has a closed list of values, neglecting the <string> value
type. The reason is practical: many stylesheet writers are used to write 
"centered" and "justified", whereas the correct values for this version 
of the draft are "center" and "justify"; catching this error in the DTD
turned out to be useful. Moreover, <string> values are poorly described 
in the draft (nothing but a reference to CSS2), and are unlikely to be 
implemented soon. (Ultimate reason: changing the attribute value back to 
CDATA is a matter of few seconds ;-)).

6. Only basic values for writing-mode are included. 

7. Three extension properties are added to enable functionality already
implemented in XEP engine but excluded from the draft:

rx:footnote-area-placement

  This is a property of a page-master. It controls the area from which
  the footnote area is subtracted in multicolumn layouts:

  "within-page" (default) places all footnotes in a single rectangular
  area subtracted from region-body, as specified in the draft;

  "within-column" creates a footnote area within the column area where
  the footnote anchor occurs;

  "within-last-column" creates a footnote area within the last column
  on the page where the footnote anchor occurs.

rx:glyph-area-height

  This property controls glyph area height calculation strategy.

  "uniform" (default) sets a single height to all glyphs in the font,
   based on ascender/descender values for the entire font, as specified
   in the draft;

  "per-character" uses actual glyph height for every character.

rx:line-count

   Specifies the number of lines affected by fo:initial-master-set;
   default is 1.
