I am encouraged and hopeful that a solution to this issue will be found
based on the "permessage" idea (as per Dale's earlier email "observer's
report").
The three cases that Tony outlines below may be used
for analysis of individual entries in the CPA.
It is not clear how the "permessage" notion will be built into the CPP.
I plan to wait to see a clear description of the solution before further
commenting.
