Yes, I would *love* to have someone figure out a plausible best-practice
story for linking and embedding RDF with XHTML content.  Specifically, I
want to be able to find RSS + Dublin Core 'whats new' feeds for any
website I knowe the homepage of. Currently RSS 1.0 aggregators don't have
any standard conventions for finding new RSS feeds. Some variant on <LINK
REL="META"... sounds plausible to me, although I understand from Sean that
we'd need to define an HTML profile to do this properly. I wonder if a
variant of the 'XHTML profile for RDF site summaries'
(http://www.w3.org/2000/08/w3c-synd/) would do the job.

I've only just now realised that multiple profiles (a space separated list
of their URI names) can be used in HTML simultaneously[1]. So there seems
to me to be no reason  why we shouldn't proceed and define a profile that
explains the link types we want and need (ie. rel=meta, plus URIs for the
existing HTML link types).
