Yes, I've looked at the xerces_j_2 branch or at least what is currently in
the repository which is about 1 month old.  Someone told me of its
existance, I think I would have prefered if this was discussed on the list
rather than in private.  It looks like the start of a new parser from the
parts that I understand.  I haven't quite figured out the validation package
yet.  The design document would be useful.  Please post a reference to it.
This could be a useful start as a basis for the new Spinnaker tree.

This sounds like the architecture of Aelfred2 where validation is added as a
layer on top of SAX2.

Glad to hear it.
