Can you give an example of how this might manifest itself? I've
already shown in a separate thread that running SPARQL queries without
paying attention to the RDF Concepts notion of equality will cause
problems, regardless of whether you use RDFa or not. And since we've
also seen that the RDFS for FOAF (for example) already allows for
values that can be either plain literals or typed literals, we know
that SPARQL queries on FOAF data could suffer from the same problem.

So do you have anything that is specific to RDFa? Also, if there is
anything, can you comment on whether the problem you foresee would be
addressed by modifying the parsing model so that either a typed
literal or a plain literal is created, depending on whether the
element being parsed has element children or not?
