The REST Adapter currently only supports the "standard" or initially proposed http verbs GET, POST, PUT and DELETE.

However REST has progressed: http://restful-api-design.readthedocs.org/en/latest/methods.html

Especially the PATCH verb is comonly used and expected by REST consumers to update individual fields of a resource. 

So it would be very useful to add support for PATCH (and possibly other REST verbs) to the REST Adapter and tools (PDSOE REST service definition).
