Its a nice to have but not required. Ie we have out spec prose for ISO
which predefines some of the tables. But, I doubt
we can just use an XML format. That said, I'd much rather maintain an
XML document then a piece of code somewhere that builds it dynamically
each time.

One thought, is there any reason to allow a user-specified data block
for each entry. I'm thinking this might be useful to hang custom algorithm
information... ie the URL pointing to the encoder to use for it. If a
vocabulary was just assigning them by element/attribute name.
