Be careful. There's two dangerous issues here:
* C++ objects
* tied objects
All the XML::Xerces objects are all thin Perl wrappers around complex
C++ objects. If you store one of these objects in an Apache::Session,
you might experience very ugly core-dumps because memory is deleted
out from under you. It might work, it might not - I've never tested it
that way. I'd like to hear how it works for you.
Also, those objects appear as hash-references because all the objects
have been tied (using tie()) to a hash in order to be able to access
C++ data members directly - there are a few Xerces-C classes, the
exception classes, that don't provide setter/getter methods.
They are *not* hashes, they just look like one, so if you attempt to
store data in them:
$parser->{some_field} = 'some_data';
You're likely to get a Perl error about 'Not able to find STORE',
because the class that implements the tied hash doesn't have a STORE()
method defined.

By definition, the parser *has* to parse the DTD if it's
specified. So, you have two choices:
1) don't include a DOCTYPE
2) write an entity resolver
If you have control over the XML files you're parsing, 1) is
simpler. If you don't, then you will have to write an entity resolver
that returns an empty InputSource to the caller when it gets a request
for a DTD.
