Sorry, somehow I truncated my message when I copied it.
What I meant to write is that I didn't find and DTD-focused
forum, so I hoped this one would do, as DTDs are often used
as a poor man's schema.

So, one workaround would be to convert the DTD to a schema
and make that chnage in the schema? Do you know if parsers
that use catalogs will let you substitute a schema for a DTD
without complaining? They are different things.

I guess that means there is no way to allow empty attributes
if the corresponding DTD declaration is enumerated, right?

Thanks again very much,
