Operation names which are identical, but defined in different portTypes are still distinct if one portType extends 
another, provided the target namespaces for the portTypes are distinct. 

However, in the GWSDL->WSDL 1.1 translation, all operations adopt the target namespace of the most derived portType and 
may collide.  

The Primer should include a cautionary note. The comment may also apply to SDE names. .
