I'm wrong.  You are correct, as per
<http://www.w3.org/TR/2004/REC-rdf-testcases-20040210/#rdf-charmod-uris>.  It
seems that, as a concequence of the unusual rules, an escaped URIRef is not the
same and the non-escaped URIRef.  Hense these two URIRefs are different:

1) <http://example.org/#Andr%C3%A9>
2) <http://example.org/#André>

Questions: Is the first URIRef represent as an actual URI as
<http://example.org/#Andr%25C3%25A9>?  Is the second URIRef represented as an
URI as the first one?

The spec seems to be using URI kinda loosely.  They are URIRefs and not URIs
themselves.

Thanks for the head's up.  :-D
