It took me so long to answer because I'm really not sure to understand. What
I can tell you is that we also want to embeed several parsers in the same
code, and that I was thinking about implementing the -P flag to flexml.

It does not look really related to your issue, now that I look more in
detail to write this mail, does it? So I guess the answer is that I don't
have any better idea ;)

Sorry about that, Mt.
