Re: [docbook] Using multiple modules

[Justus.Piater@ULg.ac.be (Justus H. Piater)]

It works, though. A very thin customization layer should get you
there. Here's what I use to make this work:

<!DOCTYPE slides PUBLIC "-//Norman Walsh//DTD Slides Full V3.2.0//EN"
  "http://docbook.sourceforge.net/release/slides/3.2.0/schema/dtd/slides-full.dtd";
 [
  <!ENTITY % MATHML.prefixed "INCLUDE">
  <!ENTITY % MATHML.prefix "mml">
  <!ENTITY % equation.content "(alt?, (graphic+|mediaobject+|mml:math))">
  <!ENTITY % inlineequation.content
             "(alt?, (graphic+|inlinemediaobject+|mml:math))">
  <!ENTITY % local.textobject.mix "|mml:math">
  <!ENTITY % mathml PUBLIC "-//W3C//DTD MathML 2.0//EN"
             "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd";>
  %mathml; 

  <!ENTITY % jpebnf PUBLIC "-//Justus Piater//DTD DocBook EBNF Module V0.1//EN"
             "http://www.montefiore.ulg.ac.be/~piater/XML/ebnf/0.1/jpebnf.dtd";>
  %jpebnf;
  <!ENTITY courseurl "http://www.montefiore.ulg.ac.be/~piater/Cours/INFO0055/";>
 ]>

Two notes:

- My own jpebnf module is derived from the DocBook EBNF Module
  V1.1CR1. It adds a little more markup and slightly more flexibility
  in the elements which I needed for didactic purposes. (Norm, why not
  augment DocBook's version in this way :-) ?) But I don't think I did
  anything special to make this work together with MathML; it should
  work just as well with the original DocBook EBNF module.

- I have not checked, but perhaps the reason it works without hassle
  is that the DocBook DTD is included later via a customization layer
  (slides). That's why I suggested above that it should be easy to
  do...

Hope this helps,
Justus
