Thanks David, that's an interesting possibility (for some other applications
too) that never occurred to me, so I'll give it a try. I'd always assumed
that parsers built some sort of index of declared ID's as a side effect of
their validating pass and so without validation turned on that wouldn't
happen. I'll do some experiments.
