 * In this test case, a CXF client sends a Username Token via (1-way) TLS to a CXF provider.
 * The provider dispatches the Username Token to an STS for validation (via TLS), and also
 * send a TokenType corresponding to a SAML2 Assertion. The STS will create the requested
 * SAML Assertion after validation and return it to the provider.
 *
 * In the second test, the service will also send some claims to the STS for inclusion in the
 * SAML Token, and validate the result.
