[tdwg-tag] Darwin Core generic XML with attributes

[Steve Baskauf]

What I'm saying is that if the XML-RDF file used as the data source 
contains only the element
<dwc:recordedBy 
rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"/>
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
<rdfs:label>Steve Baskauf</rdfs:label>
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 
thread.
