isn't this an issue about how multiple inline schemas reference each other in a   single WSDL document ?

AIUI it's just a matter of formally stating what appears to be a common practice.

Given that xs:import is defined by XML Schema and NOT WSDL, I don't see
how WSDL can really constrain it in any way.
