So, to process the HTML fragment above, a recipient would always need to 
look up the profile resource, and extract RDF triples from *that* 
document (*) first?

How do you prevent the problem we've seen with DTDs (consumers not 
willing or able to cache the resource, and thus re-requesting the same 
resource over and over again)?

BR, Julian

(*) Which specific media types would a recipient be required to support 
for profiles?
