  Hum,

 all this processing belongs to parser.c:

xmlParseCharData() calls areBlanks() to check for this and
uses the ignorableWhitespace() callback if this is the case.

The xmlIsMixedElement() is called by areBlanks(), and will
return 0 or 1 in the case a DTD is present.

But this processing is conditionned by ctxt->keepBlanks.
You can try to set it by calling xmlKeepBlanksDefault(0) before
calling the parser or creating the context.

I need a better handling for this, I will try to get this fixed
more cleanly in the next version,

Daniel
