What I'm saying is that if the XML-RDF file used as the data source
contains only the element
there is no way for AJAX, XSLT, or anything else to know that the string
for my name is "Steve Baskauf" without dereferencing the foaf.rdf file
and interpreting it. Thus the rendered HTML can't display the text
"Steve Baskauf" for a human user as the value of recordedBy.
However, including the element
somewhere in the RDF+XML file makes it possible for any of the rendering
methods you mentioned to get that information without dereferencing
another URI and without "understanding" RDF.
This was the issue which I think this got lost somewhere earlier in the
