SOAP messages naming issue

[tkrypton]

I have a strange interoperability problem where KDSoap uses different response names as the partner.
It seems to boil down to WSDL definitions like:

<operation name='Foo'>
   <input name='FooRequest' message='FooInput'/>
   <output name='FooResponse' message='FooOutput'/>
</operation>

<message name='FooInput'>
</message>

<message name='FooOutput'>
  <part name='return' type='xsd:int'/>
</message>

KDSoap generates responses like:
... <soap:Body> <FooOutput> <return>0</return> </FooOutput> </soap:Body> ...

Where my communication partner expects:
... <soap:Body> <FooResponse> <return>0</return> </FooResponse> </soap:Body> ..

From my understanding KDSoap is right, but where do I find references in the standard RFCs
to prove this?

[edit: probably nowhere, because these definitions have contradicting names?]

Thanks for any help,
Uli

I just see that my expamples got severly mangled during post. Will try to fix the post...

Now the vital XML should be readable. If not, please yell at me.
