Indeed, it would be possible to specify a complex type in XML schema
which defines exactly such pairs. However, I am not aware of had no way
to directly refer to such complex types from our logical language.
Indeed, this is the reason that XML schema complex types cannot be used
as data types in the Web Ontology Language (OWL).
