Lets say you have a RESTful Web Service.  For any given URL, you might support one or more of the HTTP verbs:  GET, PUT, POST, DELETE and so on.  A user might wonder what they mean, and which you actually support. One way of reporting that is by using the OPTION Verb.  While this is a relatively unusual verb, using it to describe a resource is a fairly well known mechanism.  I want to take it one step further.
