This probably won't work, but if you could build up a small batch and
then generate the DTD from that, then that could be your baseline. New
attribute values would have to
be "approved" -- that is, sent in to you, and you can review and
update the DTD. I guess this seems awkward for any kind of sizeable
project, especially if the attribute values are for personal names or
something like that. For projects I've worked on that have an ever-
growing list of values, we have used a database or google spreadsheets
as a source list that we can consult and add to. That's very manual,
but it works.
