For background material on anyURI in XSD see
http://www.w3.org/2000/12/xmlschema-crcomments.html#pfiIURI
anyURI was needed because of the tardiness in the IRI specification.
Also, it was strongly felt that people expect and need a URI to be the
thing you can
cut and paste from the address bar in a browser. Also XSD should follow
XML's practise in treating resolving system identifiers.
See http://lists.w3.org/Archives/Public/www-tag/2003Apr/0161.html
for other possibly interesting angles.
