I've not managed to track the whole text-v-binary discussions -  I find it
hard to find the time to keep up with xml-dev these days :-(.
Is your intention to build a performance testing framework to demonstrate
the performance difference of binary v. text XML parsers?

If so, I've been meaning to investigate the relative performances of a
variety of SAX parsers (crimson, Xerces1/2, Aelfred), both with and without
validation along with some other configurations like turning on and off of
String "interning". Plus I'd like to test the performance of a variety of
tree object models too such as DOM (crimson, Xerces 1/2), dom4j, Electric,
JDOM etc.

It might be a good idea to combine our efforts into the same benchmarking
suite so (say) it would be easy to compare a binary SAX driver fares against
the best text SAX drivers etc.

My idea was to create a SourceForge project for the benchmark suite.
Does this seem of interest or am I way off where you're at?

James
