This request is submitted by Jeff Beck on behalf of the BITS working group. It was originally submitted by Imsieke, Gerrit, le-tex" <gerrit.imsieke@le-tex.de> through the JATS List.
Request: Please add a parameter entity for global attributes. We wish to allow formatting (CSSa) and semantic (RDFa) markup in attributes.
Background: This leads to another wish: we currently patch each element that is allowed to carry an @xml:lang attribute in the following way:
<define name="sec-atts" combine="interleave">
<ref name="css_attributes"/>
<ref name="Rdfa.attrib"/>
</define>
If there were a parameter entity for global attributes in the DTD (which may default to @xml:lang), it would be easier to add orthogonal, attributes-based vocabularies.
RDFa is intended for marking up multiple-choice tests and the like. We’d prefer not to use JATS-style content-type attributes for that because RDFa is more expressive and we can use the same vocabulary in HoBoTS and in HTML (where we’ll probably have Javascript widgets that turn RDFa-enriched books into interactive test applications).
We use CSSa for conveying the original InDesign style information and local formatting overrides, after translating them into CSS properties and attaching them as XML attributes. One reason for using CSSa is that we want to be able to express formatting that should appear in the
same way in every rendering. For example, we can just pass thru the properties for handwriting fonts – css:font-family="cursive", extra spacing after paragraphs – css:margin-bottom="12pt", font color – css:color="device-cmyk(0,1,1,0)", or table cell backgrounds – css:backgroundcolor="
device-cmyk(0,0,0,0.2)". They will find their way to the HTML and EPUB renderings almost unaltered – except that they’ll translate into CSS rules or HTML style attributes, and except that color values will be converted to RGB.
