After quick discussion with Kevin Wang and Anthony Fishbeck, this design was confirmed.
DESDL ESP Services will:
(at load time) Query if logging agent provides TxIds
if no, ESP will provide generic TrxID
else ESP wil request trxid from logging agent at start of request processing
ESP will provide uniqueness components:
ESP Name, ESP node (either ip or hostname), port, threadid and method name (maybe some product name if configured)
