Mallard to HTML - MathML
Handle MathML in Mallard documents.
:Revision: version="3.8" date="2012-11-13" status="final"
This stylesheet matches embedded MathML in %{mal2html.block.mode} and
%{mal2html.inline.mode} and processes it in %{mal2html.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.

mal2html.math.mode
Output MathML and handle Mallard extensions.
:Revision: version="3.8" date="2012-11-13" status="final"
This mode is used for processing MathML embedded into Mallard 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 checks for Mallard linking using the #{mal:xref} attribute and
transforms this to a MathML #{href} attribute. It also converts #{xlink:href}
attributes from MathML 2 to #{href} attributes for MathML 3.
