Oh. I sometimes get the impression that RDFa is intended not just
for HTML but as a mix-in for other XML vocabularies too.

If it's the case that every RDFa document is an HTML document,
that simplifies things somewhat. Please make that clear
in this use case document, or in a nearby requirements wiki
topic or something headed for publication on
the http://www.w3.org/TR/ page soonish.

The nifty SWD summary suggests this October 2005 draft is current
 http://www.w3.org/2001/sw/BestPractices/HTML/2005-rdfa-syntax

Its title is:
 RDF/A Syntax
 A collection of attributes for layering RDF on XML languages

So it's pretty easy to find answers other than "you can
always follow your nose from RDFa markup thru the HTML-v-next
spec to the RDF spec".

GRDDL uses a namespace-qualified attribute on the root
element of an XML document as its hook, in the most general
case; and in the specific case of DTD-constrained HTML, it uses
the head/@profile hook.
