When I talk about reflecting from XML into RDF, I meant the constructs defined in the XML datatype spec (facets etc) not particular application schemas or data valid by those schemas. At the W3C spec level, RDF deferred datatyping issues so they could be dealt with once and for all across all XML apps by XML Schema. Now we (more or less) have this, it is natural to explore a mapping of the concepts defined in XML datatypes spec into RDF data graphs. Once some mapping has been established, applications should be able to go both ways, ie. first we reflect the XML datatype machinery into an RDF-processsable representation, _then_ we can (hopefully) reflect datatyped XML information into RDF and vice-versa.
