I agree with Ira.

Conceptually, there are at least 2 pieces of information that need to be provided.  The format/type of the input data and the desired output data.  It looks like Kaike is using the ibacm protocol as a base.  I *think* the QUERY_PATH operation for ibacm forced an SA query.  (It is used for testing purposes.  That, or I'm remembering something else and associating it with QUERY_PATH.)

The desired output data can either be encoded as part of the operation or separated into its own field.
