For a document to be a HTML 4 document it would need a HTML 4.01
document type declaration, and for a document to be a well-formed
XML document, it would have to have no HTML 4.01 document type
declaration. There are not many documents that both have and don't
have a HTML 4.01 document type declaration. Remember that the DTD
needs to match the production for external subsets.
