Existing Wording: If there are no parameters with complex types (including resources) to the operation, and the operation is idempotent (see HTTP specification definition of idempotent), the operation may be invoked by performing an HTTP GET operation where all the parameters are appended to the URL in the search portion of the URL (e.g. after the "?"). Servers SHALL support this method of invocation.

Proposed Wording: If there are no parameters with complex types (including resources) to the operation, and the operation is idempotent (see HTTP specification definition of idempotent), the operation may be invoked by performing an HTTP GET operation where all the parameters are appended to the URL in the search portion of the URL (e.g. after the "?"). Servers SHOULD support this method of invocation.

Comment:

GET invocation is a convenience method and should not be a requirement for servers to support.
