+/**
+ * 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.

language MUST use a namespace that is different than the namespace of XML
Schema. The namespace of the alternative schema language is used for element
information items that are children of the wsdl:types element information item
and for any extensibility attribute information items that appear on other
components. The namespace MUST be an absolute IRI.

either independently or together. 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.
