DocBook to HTML - MathML
Handle MathML in DocBook documents.
:Revision: version="3.8" date="2012-11-13" status="final"
This stylesheet matches embedded MathML and processes it in %{db2html.math.mode}.
The matched templates for the #{mml:math} element automatically set the #{display}
attribute based on whether the element is in block or inline context.

This template creates an HTML #{div} element for a MathML #{mml:math} element,
then outputs MathML content. It sets the #{display} attribute on the output to
#{"block"} and applies %{db2html.math.mode} to the child content.

This mode is used for processing MathML embedded into DocBook documents. For
most types of MathML content, it simply copies the input directly, except it
outputs the MathML in a way that allows the namespace to stripped for non-XML
output. It converts #{xlink:href} attributes from MathML 2 to #{href} attributes
for MathML 3.
