+/**
+ * The WSDL validator performs semantic validation of a WSDL 2.0
+ * model. Schema validation will have been performed at an
+ * earlier time so this class handles those constraints
+ * which cannot be enforced with schema.
+ * 
+ * This class also handles extensions allowing others to 
+ * plug-in WSDL validators for other namespaces and validators
+ * for other purposes.
+ * 
+ * In that, there are three phases to validation:
+ * 1. XML schema validation - performed earlier when parsing
+ *    the document in the case of an XML representation of the
+ *    model.
+ * 2. Semantic WSDL validation and extension namespace validation -
+ *    checks against the WSDL specification and other extension
+ *    specs.
+ * 3. Extension validation - extra constraints which may be 
+ *    imposed on a WSDL document. These constraints may be
+ *    from an organization such as the WS-I, naming constraints,
+ *    or any other constraints for which an extension validator
+ *    is registered.
+ *    
+ * A WSDL model is not considered valid unless all the constraints
+ * from all the registered validators pass.

If they are used together then they MUST satisfy the same consistency rules that apply to the {interface} property of a Service component and the {binding} property of a nested Endpoint component, that is either the binding refers the interface or the binding refers to no interface.
