I believe it is the intention of the WSDWG that WSDL import work the
same way as XML Schema import. So targetNamespace coercion is not
allowed. I propose we add text to the spec along the lines of;

The actual value of the targetNamespace AII of the imported WSDL MUST
match the actual value of the namespace AII on the import EII.

Given answer to Q1, not relevant.

Hope this helps
