An identity-constraint attribute field's type was resolved only among the
constraint host's descendant elements, so when the selector targets a global
element referenced from the host (e.g. unique over `.//uid` with field
`@val`), the field type was unknown and values compared lexically. Two keys
equal in value space but not lexically (3.0 and 3 for xsd:decimal) were then
treated as distinct and the duplicate was accepted.
The attribute type now resolves through the selector's target global element,
so values compare in their value space. XSTS invalid-instances-accepted
133 to 132 (idF010), no other bucket moved.
