This interceptor handles parsing the StaX WS-Security results (events) + checks that the
specified crypto coverage events actually occurred. The default functionality is to enforce
that the SOAP Body, Timestamp, and WS-Addressing ReplyTo and FaultTo headers must be signed,
and the UsernameToken must be encrypted (if they exist in the message payload).
Note that this interceptor must be explicitly added to the InInterceptor chain.
