Are you sure about this?  From my reading of section 3 of the
XMLVers PEN you cite above, I'd say that

   http://ivoa.net/xml/VOSITables/VOSITables-v1.0.xsd

should stay where it is, the new schema should be added as

   http://ivoa.net/xml/VOSITables/VOSITables-v1.1.xsd

and then
   
   http://www.ivoa.net/xml/VOSITables/v1.0

should be changed to redirect to the new
http://ivoa.net/xml/VOSITables/VOSITables-v1.1.xsd
rather than the old
http://ivoa.net/xml/VOSITables/VOSITables-v1.0.xsd


As a separate issue: the document currently residing at
http://ivoa.net/xml/VOSITables/VOSITables-v1.0.xsd and hence
http://www.ivoa.net/xml/VOSITables/v1.0 doesn't look right to me:
I'd expect to see the schema from A.3 of VOSI 1.0,
but it's different, e.g. the top-level xsd:schema/@targetNamespace is
http://www.ivoa.net/xml/VOSICapabilities/v1.0 rather than
http://www.ivoa.net/xml/VOSITables/v1.0.
Am I going mad?  (quite possible - I feel my sanity draining
every time I think about XML namespaces).
