You appear to be saying that >rdf:XMLLiteral is now a datatype just like all other datatypes (except that >it is hard-coded into RDF in terpretations). However, in Section 3.1 of >http://www.w3.org/2001/sw/RDFCore/TR/WD-rdf-mt-20030117/ (dated 18 May >2003) I still see wording to the effect that there is special meaning given >to language tags for typed literals with datatype rdf:XMLLiteral. I do not >view this as a satisfactory state of affairs. Yes, you still see that wording because we are still arguing slightly about the *exact* way that XML literals will be described, and I do not want to rewrite the document more times that I absolutely must. Nevertheless, the decision to remove lang tags from XML typed literals has been taken and will be implemented, as I said in my message. If you prefer, we will wait for your response until the relevant edits to the document have been completed. I will send you another message to trigger this issue, with the same subject line.
