That'd probably work. I may take a look at how much performance can be 
gained by going this way. I've got an internal parse event stream 
representation of documents (currently going to and from SAX2, because I 
wanted compatibility with other tools) that I could easily modify to use 
the CharSequences.

Yes, this has been a major screw-up in XML API design since namespaces 
got pasted on top of XML. I hate to think how many separate 
implementations of namespace tracking code have been written - I'd 
suspect it's in the dozens, at least.

I'm not all that big on StAX, given the glacial progress, but if it 
doesn't hurt the size and performance of using the base code there's not 
a problem. Can you layer it so that the StAX API uses separate classes? 
That way different build targets could build just the base XMLPull (+ 
the changes we're discussing) API or the full StAX implementation.
