I can think of two ways to do this, each of which might be appropriate in a
different situation.  (Both could read the same profile of XML with no
problems as well.)

1) A 'parser' that just reads the document and spits out events without
attempting to interpret them.  It might be smart enough to identify
document parts (like DOCTYPE, or identifying &entity; as an entity), but
wouldn't check the structure at all.  It would just read with no concern
for the structure of what it read.

2) A parser that only read a canonical form of XML, 100% normalized, with
no DOCTYPE information to create entities or specify defaults.

Both are interesting projects.  1 would let higher levels of the app fill
in the gaps, while 2 would be more limiting, though 2 might feel more in
the spirit of XML.
