There would be a little speed difference from not having to check for defaulted attributes.
The half-baked parser might also be able to directly point to the xml input without having to
copy it, i.e. use start-length pointers for the tags and attrs. This would be more
cumbersome if there was less of a one to one correspondence between the raw xml and what you
got after expansion and defaulting.

Detecting the prologue and loading an alternate module takes a few lines of Java code.
Prologue processing, entity expansion and attribute defaulting take up a little more than
that in the parsers that I've looked at.

I'm not sure I understand. Could you elaborate on how you cheated :-?
