Hmmm, yes. I guess we need to lose at least one of: (a) URIs are nodes (b) strings are nodes (c) URIs are strings (d) literal nodes denote themselves I think you're saying that dropping (c) doesn't wash. Not having thought this through, I'd been going with the idea that URIs are string-like things distinguishable from strings. Which I now see is a bit like the XML datatype troubles you mentioned. Hmmm... <xsd:string,"string"> denotes "string" ? #g ------------------- Graham Klyne <GK@NineByNine.org>
