It would seem to me that ALL the "syntax sugar preprocessing" --
entity resolution and substitution, CDATA section processing, attribute
default value insertion, maybe XInclude resolution -- belongs 
in some preprocessor step.  Then parsers per se can be clean lightweight things 
that don't understand all this stuff (and machine-produced XML can write
for), whereas human-authored XML can go through one or more of these
preprocessors to get it into shape for parsing.
