My DTDCrunch might do more than you want: it crunches a (potentially multi-file)
DTD into the minimal information required by a non-validating parser.  Entity
declarations are preserved; attribute declarations are preserved unless they are
of type CDATA and have no default value; element declarations are preserved only
if the element has element-only content, and then in the trivial form
<!ELEMENT foo (foo)>.  There is one declaration per output line.
