Topology Awareness of CP-CP Sessions

Due to some confusion about the interpretation of the 'CP-CP Session
support and status' field in the TG Characteristics (X'47') Control
Vector, a clarification has been made to the description of the 'CP-CP
Session support and status' field in the TG Characteristics (X'47')
Control Vector and to the description of the 'Topology awareness of CP-CP
sessions supported' field in the CP Capabilities (X'12C1) GDS Variable.

Previously, the two bit 'CP-CP Session support and status' field
in the TG Characteristics (X'47') Control Vctor indicated if CP-CP
sessions were:

 supported and active
 supported and not active
 not supported and not active

The subject clarification further specifies that it is the TG record owner's
contention-winner CP-CP session that is active or not active.

The file, arch8419.psbin contains these changes (marked with a '|'
in the left margin) and has been placed on the
networking.raleigh.ibm.com file server in the
/pub/standards/aiw/appn/architecture directory.

This item will be included in the AIW12 Architecture Reference SIG
agenda.
