To build on this a little, the "class" and "title" attributes do not 
imply semantics or meaning any more than any other string of characters 
does. The microformats community/process/standards *defines* certain 
"class"es and "title"s to have meaning in certain contexts.

As Ernie implies elsewhere, the semantic meaning should be fairly clear 
because the tendency is to pick names that have real meaning, either 
from existing standards or from real live usage on the web.

As mentioned in my previous message, "urn" will not work unless you're 
willing to sacrifice XHTML/HTML 4.01 compliance.

Regards, etc...
