It might well be, but my interest is in metainformation is limited. I 
spotted a potential weakness in how XHTML2 handles it that could be 
fixed. If someone who is already on that list wants to get comments 
from the Dublin Core people, feel free, but I was using Dublin Core 
more as a real world example of an existing metainformation profile to 
point out a weakness in how XHTML2 handles metainformation and to 
suggest a possible solution, not because of any interest in Dublin Core 
per se.

This is a kludgy hack that assumes that Dublin Core has exculsive use 
of <link rel="schema.DC" /> and <meta name="DC.*" />. It breaks down if 
an author also uses another metainformation schema that does not 
respect what Dublin Core tries to reserve for its own purposes. Given 
the limited ways of specifying metainformation schema in HTML/XHTML1 
it's probably the best that could be done, but it still is a kludge.
