Same for me. I've just found the framework w3c has used for benchmarking:
However the hard part seems not building a parser (it seems rather
compact and compression is made using standard DEFLATE after block
reorganization, so the hard work is free), but building the necessary
event grammars for optimized token econding. Besides I haven't
understood how effective and practical could be using learnt grammars:
if we use generic events + qnames and attnames EXI loses a great part
of its compression power, if we stick to grammars we run the risk of
losing the X in XMPP
