A draft proposal for support of secondary information is now
  available via anonymous ftp at ibmstandards.cary.ibm.com under
  '/ciw/sig/2rc/si-ad.ps'.

  Changes made to the original contribution, distributed at the
  September CIW, are summarized as follows:

  1. CPI-C-defined secondary information is listed and assigned
     with numbers.

  2. The program has to receive secondary information in a
     piecemeal fashion because of its unbounded length.
     Extract_Secondary_Information (CMESI) now works like the
     Receive call:

        CMESI(conversation_id,    /* input  */
              call_id,            /* input  */
              buffer,             /* output */
              requested_length,   /* input  */
              data_received,      /* output */
              received_length,    /* output */
              return_code)        /* output */

  3. Secondary information is maintained in different manners:
     a) For conversations using conversation-level non-blocking,
        secondary information is kept:
        - On a per-conversation basis for conversation calls.
        - On a per-thread basis for non-conversation calls.
     b) For conversations not using conversation-level non-blocking,
        secondary information is kept:
        - On a per-queue basis for calls that are associated with
          a conversation queue.
        - On a per-thread basis for calls that are not associated
          with any conversation queue.

  4. The proposal also addresses the case of an unassigned
     conversation ID and an alternative solution of using OOID as
     the handle for retrieving secondary information.  The proposed
     solution also takes into consideration of callback function.

  I would appreciate your comments on this proposal as soon as
  possible.
  (Please send your comments to [email-masked])

  If I don't hear any objection by 10/15, I will submit a request to
  the CIW for consideration of granting an AD status on the proposal
  by 10/29.
