PrimitiveAssertion
This class represents an assertion without any attributes or child elements (in particular
without a nested Policy element).
The AnonymousResponses or NonAnonymousResponses assertions in the addressing metadata namespace http://www.w3.org/2007/01/addressing/metadata are examples of this type of assertion. The implementation of the equal and normalize methods in the class are trivial, and there should be no need to extend this class.
