Ok so as I understand it the new API will work as Expat does (I think).
You get attributes that were explicitly set in the input stream first,
then you get the ones which were defaulted in because of the DTD, and
there is a count which tells you where the changeover point in the list
is.  That is the kind of behaviour I would be looking for, I wasn't sure
what the current 'SAX1' behavour was.

Graham.
