"The only solution we currently see is to be well formed and run without a
DTD. We would really like to have a DTD so that we can take advantage of
validation and authoring tools."
As Eliot points out, you can also do this with architectural forms. I
attribute this to the fact that they were designed in the 1990s instead of
the 1980s (like the rest of SGML) and I further feel that part-wise
validation should be part of any new schema language, including a revision
of DTDs.
