ACTION Reagle: ask schema WG if URI="#ref" a valid instance of the uri schema type. ACTION Eastlake: Otherwise, leave it as is and add a sentence or two clarifying thte IDREF must be processed like an XPATH.
Not a technical problem, but no longer a compelling editorial reason to keep it if we aren't going to properly profile it. XSLT's are going to have to be c14n'ized as well (c14n before or after XSLT? Not sure). ACTION Eastlake: add a sentence to the XSLT explaining this.
No WG calls before FTF.
