I looked at the dtd in XMLSpy and elsewhere and it does seem to be
incorrect... can anybody help me out here?

That's an HTML DTD, so it's no wonder that an XML parser cannot parse it.
Try using an XHTML DTD, such as
<http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd>.

Ok, but it's still a dtd and has to conform to rules for dtd format.
Why the parse error? I thought a dtd was a dtd...? Thanks for the
help by the way.

There are SGML DTDs and then there are XML DTDs. HTML is an SGML
language, so it has an SGML DTD. XHTML is an XML language and has an XML
DTD.

XML is a subset of SGML, so an SGML parser can parse XML documents and
DTDs, but in general an XML parser cannot parse SGML documents and DTDs.

For example, in SGML it's OK to put comments inside entity declarations
(delimited with double hyphens: --this is a comment--), but in XML this is
forbidden. It is just such a comment that your XML parser is rejecting.
