This seems to be a bug. At some stage the spec was changed so that a DTD
type of IDREFS no longer causes the attribute to have the type annotation
xs:IDREFS, and implementing this change in Saxon apparently caused the
idref() function to stop working on attributes defined as IDREF[s] in a DTD
(as distinct from a schema).
