[wsrp] MTOM/XOP implementation

Title: [wsrp] MTOM/XOP implementation

Here is the w3c list of MTOM/XOP implementations to support the recommendations:

http://www.w3.org/2000/xp/Group/4/08/implementation.html#impls

Note that these are all SOAP 1.2 so we may wish to define two new protocol bindings: _SOAP1dot2 and _SOAP1dot2withMTOM for WSRP 2.0.

Axis2 and Microsoft's Indigo have announced planned support for MTOM/XOP and here is a reference which suggests JAX-RPC 2.0 will include MTOM: https://jax-rpc.dev.java.net/whitepaper/1.1.2/attachments.html. 

No idea if these and other implementations will interop from day one.
