+      # +api+ must be an ActionWebService::API::Base derivative, and

+      # will be sent with HTTP POST.
+      #
+      # Valid options:
+      # [<tt>:namespace</tt>]    If the remote server has used a custom namespace to
+      #                          declare its custom types, you can specify it here. This would
+      #                          be the namespace declared with a [WebService(Namespace = "http://namespace")] attribute
+      #                          in .NET, for example.
+      # [<tt>:driver_options</tt>]    If you want to supply any custom SOAP RPC driver
