We are all trying to figure out what is going on here :-).

Mm... okay. I am using SUDS. So far I have found two bugs in SUDS. It is 
quite likely that there are more.

This strikes me as incorrect. I would expect a default namespace 
declaration or an explicit namespace in front of the requesterNSA, 
providerNSA, and reservation elements.

But I could very well be wrong.

Since you have tried two different implementations it does point to the 
SOAP stack I'm using. However my impression from reading the WSDL manually 
is that everything under the <ns6:reservation> should be under the 
xmlns:ns6="http://schemas.ogf.org/nsi/2011/07/connection/types namespace 
as well.

John, can you comment here?

This is my first venture into WSDL as well, so I am puzzled as well.

+1 from here as well.
