Wouldn't this break existing pre-RDFa uses of CURIE-like tokens?

Uses of "dc:blah" with no explicit prefix mapping are not uncommon.  
(Admittedly more in meta@name than @rel.) I'd say they're almost  
certainly more common than the full-URIs-in-rel that this solution is  
designed to work around.

eRDF pages will often also contain rel values with colons in. eRDF  
does map prefixes to URIs, but not via xmlns:foo, instead using an  
RFC2731-style <link> element.

In both of those cases, you'll end up with incorrect triples that use  
bogus URL schemes.
