I would view any such change in a >negative way. Just to clarify: as of my last message, there are no changes to any RDF entailments now being proposed. The only change, apart from tightening up the wording in places, is that the D-semantic conditions now only require that literal values of literals in the actual vocabulary are in LV. This brings the D-semantic conditions in line with the other conditions in a way that Herman requested, but makes no difference to any any entailments. The class extension of a datatype name is the value space of the datatype.
