              <p> The basic interaction pattern from which all others are composed is "one-way". In
                  this pattern a source sends a message to a destination without any further
!                 definition of the interaction. "Request-response" is a common interaction pattern that
!                 consists of an initial message sent by a source endpoint (the request) and a
                  subsequent message sent from the destination of the request back to the source (the
!                 response). A response in this case can be either an application message, a fault, or any
!                 other message. Note, however, that reply messages may be sent as part of other
                  message exchanges as well, and are not restricted to the usual single Request,
!                 single Response pattern, or to a particular WSDL transmission primitive or MEP. The contract between the
!                 interacting parties may specify that multiple or even a variable number of replies
!                 be delivered. </p>
              <p> The set of message addressing properties defined in this specification is sufficient
!                 for many simple variations of one-way and request-response MEPs. More advanced MEPs may
!                 require additional message addressing properties to augment the facilities provided

              <p> The basic interaction pattern from which all others are composed is "one-way". In
                  this pattern a source sends a message to a destination without any further
!                 definition of the interaction. "Request-response" is a common interaction pattern
!                 that consists of an initial message sent by a source endpoint (the request) and a
                  subsequent message sent from the destination of the request back to the source (the
!                 response). A response in this case can be either an application message, a fault, or
!                 any other message. Note, however, that reply messages may be sent as part of other
                  message exchanges as well, and are not restricted to the usual single Request,
!                 single Response pattern, or to a particular WSDL transmission primitive or MEP. The
!                 contract between the interacting parties may specify that multiple or even a
!                 variable number of replies be delivered. </p>
              <p> The set of message addressing properties defined in this specification is sufficient
!                 for many simple variations of one-way and request-response MEPs. More advanced MEPs
!                 may require additional message addressing properties to augment the facilities
