The scoping rules for SML identity constraints should be aligned with how they
are defined for XML identity constraints. The referenced key should be located
by walking the chain of ancestors (starting at self). The first such key found
should be used for this purpose. This allows it resemble how
primary-key/foreign-key relations are defined for databases.
