WSDL queries

[tans]

1. Can we have a WSDL file with no bindings?
2. What is the main difference between an Interface and a Binding?Are Bindings and interfaces necessary for a service?
3. Is there any specific validation done for Namespaces?

Well this might answer my question myself....
1. We can have a WSDL file without bindings.One point to remember here is bindings cannot exist without an Interface.
2. Interface determines 'WHAT' is provided by a service.
Binding determines 'HOW' to access the service.
Access Points or End points determine 'WHERE' it can be accessed.
Its like,Operations and signature details like Input and Output response params are what an interface expresses.
And Encoding types like Transport or Message level is expressed by Bindings.
So service can exist even without interfaces and bindings.
3. Any format is accepted for namespace.There is no validation done for namespaces....( not sure on this point)
