C.3 Extension Elements

WSDL has an open content model. It is therefore possible for an extension to define new components. The XPointer Framework scheme for components added by extensions is:

extension(extension-namespace, extension-specific-syntax)

where extension-namespace is the namespace that identifies the extension, e.g. for SOAP the namespace is http://www.w3.org/2003/03/wsdl/soap12, and extension-specific-syntax is defined by the extension. The owner of the extension must define any components contributed by the extension and a syntax for identifying them.
