true, but
* FastParser doesn't use XDTDHandler, it's only used with the "old" 
expatwrap parser that isn't "fast".
* XDTDHandler is only for unparsed entities, whereas here internal 
entities would be required and those are always parsed entities

there isn't any UNO API for internal entities.

the internal entities should be handled by libxml2 itself, the problem 
is that the DTD isn't read (it's not bundled?) so they aren't declared.

so i guess you could either figure out how to get this DTD bundled (note 
that there are different versions of MathML, and that you should ask 
your local Debian Developer what they think about its license before 
bundling it), or to provide these entities as built-in via some hook as 
Noel proposed in
