WSDL Definition Problem - wsdl

Question

We have been given a .wsdl file (listing below) which we will be using to generate c# code for use in our app. When I load the file into xmlspy I get the following error
attribute 'type' in message part 'organisation' (message 'getOrganisationResponse') refers to type 'organisation' which is not defined within the WSDL file!
It says it can't find the type but this is defined in the section at the top of the file, so I'm not sure why it does not find it.
Any help would be appreciated
Cheers
Richard

Your type declarations underneath <types> need to be given their own namespace. I'm guessing that the supplier of your wsdl either used an extremely lax parser when testing the WSDL they wrote or relied on some code first WSDL generation tool to create this WSDL. In either case, the onus is on them to get you a properly conforming WSDL and xsd.
Here is an example of what the relevant parts of that WSDL should look like - change the namespaces here as you wish:
