  Right, XLink is intended to be processed after parsing (at least
logically), and a validating parser should not care about the content
of an xlink:href it should just be declared as CDATA in the DTD used
for validation.

  Schemas or specific validation tools may verify that this conforms to
the URI-Reference syntactic constraints. Checks that the resource is
valid could be done using a link checker but it is expected to take place
at a later stage.
