Note that "...representing an absolute URI with optional fragment identifier * when subjected to the encoding described below *". URIRef allows characters that URI doesn't. The explanation: "Note: this section anticipates an RFC on Internationalized Resource Identifiers. Implementations may issue warnings concerning the use of RDF URI References that do not conform with [IRI draft] or its successors." i.e. "we wanted to use IRI, but it hadn't finished". Damian
