/**
 * A test suite for scenarios where the internal MessageContext is converted
 * between handler context formats (SOAPMessageContext and LogicalMessageContext).
 * 
 * The flows that need to be tested here are:
 * 
 * 1) INBOUND: The MessageContext will be converted from a LogicalMessageContext
 *             to a SOAPMessageContext.  This drives converting the OM message 
 *             to an SAAJ SOAPMessage among other things.
 *    
 *    specific tests:         
 *    - Normal message
 *    - Fault message
 *    
 * 2) OUTBOUND: The MessageContext will be converted from a SOAPMessageContext 
 *              to a LogicalMessageContext.  This will drive conversion from 
 *              an SAAJ SOAPMessage back to an OM (there are some very tricky 
 *              pieces of code contained within that scenario). 
 *              
 *    specific test:
 *    - Normal message
 *    - Fault message
