%mathml.hook; appears out of place to me.  I can see that defining
%mathml.hook; as "| mathml" would make a valid content model, but it
seems odd that the "|" is part the model group in the <equation>
definition, not part of a model group contained in %equation.content;,
which is where %mathml.hook; is referenced.

What about:

<!ENTITY % equation.content "(alt?, (graphic+|mediaobject+%mathml.hook;))">


Will %mathml.hook; be also added to <informalequation> and
<inlineequation>?
