The precisionDecimal type was in earlier XSD drafts. I guess that's how it got onto our list of types to review. Apparently it then got shoved off into a separate NOTE, for whatever reason. Today's resolution doesn't mention it, and I don't think we need to do anything about it. In RDF you MAY use whatever datatypes you like anyways, including this one.

Best,
Richard
