DTD for XSL Formatting Objects

<?xml version="1.0" encoding="iso-8859-1"?>
<!-- 
 This DTD has been developed in order to validate XSL FO documents 
 conformant to XSL WD of March 27, 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: 
 xmlns:rx="http://www.renderx.com/XSL/Extensions".

INTRODUCTORY NOTES
1. As compared to the draft of 1999年04月21日, 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: it works 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-graphics, as these may 
contain elements outside the FO namespace. 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.
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. 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:footnote-area-placement
 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.
