I suppose that (one or more) RDF file(s) could be returned as part
of the AX discovery.. and the RDF's would have the attributes
that are supported by the OP.

I was just concerned about prompting a user multiple times
for the same data, but if an RP can discover the supported
attributes before requesting them, then that should cover it.
