(Correct me if I'm wrong, but my understanding is that MathML /is/ XML, 
and any character entities it references must be declared in the DTD. 
It is just that xmlreader, which "supports a subset of XML features, but 
is fast and small" (xmlreader/README), does not process an XML file's 
doctypedecl.  It surprises me a bit to learn that MathML import would 
use the known-incomplete xmlreader.)
