No, it can't be done. DTDs don't provide any way to specify numeric
ranges. (Unless your range is something small like 1-5, in which case
you could possibly list all the legal values.)

The workaround is to use a different schema language, or check the
value in your application.

A DTD does not allow that. The W3C XML schema language however allows it
using the min/maxInclusive or min/maxExclusive facets:

Don't think you can do that in a DTD, though you can in a Schema.

Which is one of many reasons to consider moving to schemas.

But remember, DTDs *or* schemas are only an initial sanity-check stage
-- "higher-order syntax". It's always assumed that the application is
going to have to enforce semantic constraints.
