The RDF Core WG is chartered to complete the work on RDF vocabulary
description present in the RDF Schema Candidate Recommendation.
RDF Schema must be expressed in terms of the RDF model, and must use W3C
RDF syntax. RDF Schema must use and build upon XML Schema datatypes to the
fullest extent that is practical and appropriate. Specifically, the RDF
Core Working Group is not chartered to develop a separate data typing
language that duplicates facilities provided by XML Schema data types.

The charter leaves us a certain amount of flexibility. Making sure that an
XML-friendly RDF representation of datatypes is possible using RDF Schema
or its extensions (eg. Web Ontology work) is clearly a duty of this WG.
How much of the detailed work on RDF datatyping actually gets done within
RDF Core isn't rigidly specified by the charter.

The old RDF Schema spec handwaves pretty badly on this, since XML Schema
didn't really exist back then. We're now in a position to do a tighter

For my part, I've been absent from much of the RDF Core discussions for a
month or so, and am this week trying to digest the various lengthy
discussions on Literals etc. and understand how they relate to the options for
datatyping in RDF Schema...
