I'd be willing to work with someone in publishing a version of XHTML
(using the modularization framework) that included Dublin Core. Sean,
either you or someone else can take this offline to me and we can
discuss the particulars. I'll be happy to publish the results with
an ownerid of "-//", so people can begin using it, and
if some standards body is interested we can perhaps write it up as a
NOTE (although my time for the prose production would be extremely
limited right now).
