Document looks like HTML, ignored

[Toby Inkster-4]

"Document looks like HTML, ignored" error attempting to validate
<http://purl.org/NET/book/isbn/0596000278>.

The Redland parser <http://librdf.org/parse/> is able to handle it fine.

Possible reason: it includes a <title> element - the default namespace
is http://purl.org/dc/terms/ - so this is a perfectly valid thing to do.
