For the record: I'm still VERY unhappy with the fact that RDFa imposes a 
syntax on the rel attribute that is likely to be incompatible with the 
way it's used elsewhere (sticking plain URIs into it).

Requiring CURIEs for *new* attributes is fine, but imposing a 
potentially non-backwards compatible syntax onto existing attributes is 
an entirely different story...
