/**
 * The <code>org.apache.axis2.jaxws.core.MessageContext</code> is
 * an interface that extends the JAX-WS 2.0 <code>javax.xml.ws.handler.MessageContext</code>
 * defined in the spec.  This encapsulates all of the functionality needed
 * of the MessageContext for the other JAX-WS spec pieces (the handlers 
 * for example) and also provides the needed bits of contextual information 
 * for the rest of the JAX-WS implementation.
 * 
 * Specifically, this is responsible for providing APIs so that the client 
 * and server implementation portions can get to the Message, defined by the 
 * Message Model format and also any metadata that is available.
