I think there is some confusion regarding the way Dublin Core metadata 
is presented.

The page contains e.g.

<meta name="DC.Title" lang="fr" content=" .: Une Cerise au potager - 
&eacute;levage de lapins angoras en Alsace:. " />

The name DC.title is *not* registered or even mentioned at
http://wiki.whatwg.org/wiki/MetaExtensions
Instead, dcterms.title is, with a reference to
"Expressing Dublin Core metadata using HTML/XHTML meta and link elements",
http://dublincore.org/documents/dc-html/
which in turn mentions DC.title but not dcterms.title.

If there's a mistake here, it has been in the process of defining DC 
things in the wiki, rather than in implementing the wiki table in 
validators.

I guess you could register DC.title (and similar names) in the wiki, 
with reference to the cited document. I don't see why that would be 
useful, since Dublin Core metadata seems to be just write-only code on 
web pages, but it would solve this technical problem, in due time.
