+// TODO: should request and response payloads implement validation?
+// Sort of makes sense to run validation over the request at this level, at least for spec
+// compliance, though perhaps handlers may want to be more relaxed with validation.
+//
+// Should the response object run through validation?  What is a valid response may change as
+// the spec changes.  Maybe this should just be handled by spec compliance tests.

+// This operation requests the server to generate a new symmetric key as a Managed Cryptographic Object.
+// This operation is not used to create a Template object (see Register operation, Section 4.3).
+//
+// The request contains information about the type of object being created, and some of the attributes to be
+// assigned to the object (e.g., Cryptographic Algorithm, Cryptographic Length, etc.). This information MAY be
+// specified by the names of Template objects that already exist.
+//
+// The response contains the Unique Identifier of the created object. The server SHALL copy the Unique Identifier
+// returned by this operation into the ID Placeholder variable.
