After repairing two errors in your instance (see below), it is indeed
schema-valid. The reason is that selected elements are not required
to have the fields specified by unique and keyref: if they lack one or
more of them, they are just ignored. If you want every selected
element to be required to have all its fields, use key instead of
unique. There's no way in the identity constraint itself to require
all elements selected by a keyref to have all their fields, but in
this case you can of course just make the attributes themselves
required.
