Re: Not waiting on browser manufacturers for RDFa 1.1

Which is EXACTLY why we rejected it as a required format.  If it's 
something you want to support in your implementation, I say go for it.  
But I think it is way too high a risk.  I would MUCH rather have this 
flash hack coupled with a CORS-aware proxy as a backup service.  At 
least this way we are only delivering (X)HTML files that are then being 
parsed.  No room for random stuff to be injected into my Javascript 
runtime environment.
