Well that's interesting. To be honest, I didn't know that regex field
definitions were possible in conformance profiles, I've never used that
feature. I'm almost positive that HAPI doesn't support it, but it would be
very easy to add. (I can help in any way you like if needed)
It sounds like you've got a good solution in mind, I guess the only
outstanding thing is the issue of cross checking values like the EVN-1
example you gave. I guess the simplest way to do that would be to write your
own Validator with if/else checks in it (I'm assuming that's what you
already had in mind :) ). It would be really nice to come up with some way a
bit more automated to do it (XML definition files and a parser for instance)
but I don't know that this would end up being very flexible.. who knows?

I guess the big advantage to using conformance profiles is that if you
decide you want to do compile time validating in the future, you can get at
least some of it from the conformance classes generator in HAPI.
Good luck!
Cheers,
James
