/**
* Validate security in an Inbound SOAPMessage.
*
* Calling code should create com.sun.xml.wss.ProcessingContext object with
* runtime properties. Specifically, it should set SecurityPolicy, application
* CallbackHandler Or a SecurityEnvironment and static security policy context.
* The SecurityPolicy instance can be of the following types:
*
* - A concrete WSSPolicy
*
- A MessagePolicy
*
- A DynamicSecurityPolicy
*
*
* A DynamicSecurityPolicy can inturn resolve to the following:
*
* - A concrete WSSPolicy
*
- A MessagePolicy
*
*
* For cases when policy resolution does not happen accurately because the
* identification context was not available - for eg. operation name in
* the message is encrypted - resolution can happen to the enclosing
* container configuration.
*
* Policy resolution can happen as follows:
*
* (a). Constructed StaticPolicyContext - identifying context associated with
* configured security policies - is used for look-up of configured
* MessagePolicy/DynamicSecurityPolicy/WSSPolicy instances
*
* (b). NOTE: Relevant only when the SecurityPolicy is an ApplicationSecurityConfiguration, or the
* root element of the Security Configuration file that was used to generate the SecurityPolicy is
* <xwss:JAXRPCSecurity>
*
* In case an identifying context can not be constructed because such
* context has partly to be inferred from the message (for eg. operation
* name contained as the element name of SOAPBody), the resolved container
* configuration is used as follows:
*
* If C = {p1, p2....pn}
* where pi belongs to collection of MessagePolicies held by the container.
*
* an in-bound message is processed without application of a policy, whence
* a policy representation of the metadata contained in the security header
* is constructed as each header element is processed (iteration).
*
* If P be such policy (MessagePolicy) that gets built upon each iteration, C
* is reduced as follows:
*
* redux (P, C, M)
*
* where M is the SOAPMessage and
*
* redux:
*
* (1). eliminate all pi that are not loosely semantically equivalent where
* the equivalence is checked as follows:
*
* (a). SignaturePolicy: equivalence of FeatureBinding and KeyBinding
* excepting target bindings contained in its
* FeatureBinding
*
* (b). EncryptionPolicy: equivalence of FeatureBinding and KeyBinding
* excepting target bindings contained in its
* FeatureBinding
*
* (c). AuthenticationTokenPolicy: equivalence of Feature and Key Bindings
*
*
* (2). eliminate all pi whose target bindings contained with the FeatureBindings
* are applicable to the message. Note that all required message parts should
* be apparent post-processing, therefore, equivalence of target bindings
* would be checked by comparison of Node sets of SOAPMessage constructed
* using the inferred and those contained in C.
*
* After every such reduction, an attempt is made to resolve the policy identifier
* (operation name) that can be used for policy resolution, which should be contained
* in C and is used further for message processing.
*
* @param context an instance of com.sun.xml.wss.ProcessingContext
* @exception com.sun.xml.wss.XWSSecurityException if there was an unexpected error
* while verifying the message. OR if the security in the incoming
* message violates the Security policy that was applied to the message.
* @exception WssSoapFaultException when security in the incoming message
* is in direct violation of the OASIS WSS specification.
* When a WssSoapFaultException is thrown the getFaultCode() method on the WssSoapFaultException
* will return a QName which would correspond to the WSS defined fault.
