I fully agree.

This text is completely orthogonal to RDFa. I think references to RDFa should removed, saying something like

"""
When @role is included in a markup language, a Processor that 
generates RDF triples from the data MUST process the role values as follows:

 * The subject is the value of @id if present. Otherwise the subject is
   a unique newly created bnode.
 * The predicate is the term role in the vocabulary defined at
   http://www.w3.org/1999/xhtml/vocab.
 * Each value of @role is an object, forming an RDF triple with the
   subject and predicate defined above.
"""

That processor may be a separate parser that puts RDF triples into an API Store, just like an hCard parser in our examples. Similarly to that hCard processor, the role processor has nothing to do with the RDFa attributes, though the generated triples may merge with the rest through the API. It is fine (and actually useful) to refer to this 'Store level merge' possibility in the text to show how the different processors may meet...
