2.18 QName resolution

In its serialized form WSDL makes significant use of references between components. Such references are made using the Qualified Name, or QName, of the component being referred to. QNames are a tuple, consisting of two parts; a namespace name and a local name. For example, in the case of an Interface component, the namespace name is represented by the {namespace name} property and the local name is represented by the {name} property.

QName references are resolved by looking in the appropriate property of the Definitions component. For example, to resolve a QName of an interface (as referred to by the interface attribute information item on a binding), the {interfaces} property of the Definitions component would be inspected.

If the appropriate property of the Definitions component does not contain a component with the required QName then the reference is a broken reference. It is an error for a Definitions component to have such broken references.
