Actually, this is a point noted as ambiguous by Xerces-J [1]:

"We have interpreted the specs as requiring <keyref> Identity
Constraints to refer to <key> or <unique> identity constraints within
the scope of the elements to which the <keyref> is attached. This
interpretation is at variance with the Schema Primer, which contains an
example with a <keyref> declared on an element used inside the element
of its corresponding <key>;"
