[docbook] XML Docbook validators?

[Neil Roeth <neil@occamsrazor.net>]

I don't know of a validator that will parse that form of comment, butI did
notice that if I download that xhtml DTD from www.w3.org, I get this format:

<!ENTITY % ContentType "CDATA">
    <!-- media type, as per [RFC2045] -->

which is different than your example and should parse just fine.  Perhaps
you're not using the current version of the DTDs?
