Something like that. The Community is crying out for hard figures rather
than speculation, so when people's implementations are ready and tuned to
the hilt, I'd like to organise a race.

For now, I'm collecting ideas on testing procedures that will ensure

Validation on and off - I forgot about that - another criteria for my
list :-)

Oooh, that'd be sweet. The binary implementations aren't very ready yet,
but the testing tools will be useful for comparing different parsers for
now, and they can be designed to allow plugging in binary formats later
easily (this may come for free if they support multiple implementations
