 * Test the various conditions in the matching algorithm
 *  1 - FAIL if there are intents that are mutually exclusive between reference and service
 *  2 - PASS if there are no intents or policies present at reference and service
 *  3 - FAIL if there are unresolved intents (intents with no policy set) at the reference (service should have been checked previously)
 *  4 - PASS if there are no policies at reference and service (now we know all intents are resolved)
 *  5 - FAIL if there are some policies on one side but not on the other
 *  6 - PASS if the QName of the policy sets on each side match
 *  7 - FAIL if the policy languages on both sides are different
 *  8 - Perform policy specific match
