Thanks again. As for your suggestion about DoV - we will probably see what we capture in QA Spec and then figure out whether we need to say more. One of the reasons I'm favoring a Note, is that this may be of interest to people, outside the scope of QA Spec. However, we plan to solicit other opinions on the usefulness of DoV. regards Lynne 10 PM 6/18/2004 +0100, Jeremy Carroll wrote: >Correct numbers: > >2 required > >9 not recommended > >34 optional! > >(note this includes rdf:XMLLiteral as an optional, so the total should be >one more than the number of XML Schema builtin simple datatypes) > >(I have opted for "seventeen billion" rather than >"17179869184" as the value of 2^34) > > >>>[[ >>>One WG decided to use the built-in datatypes from XML Schema in their >>>specification.
