As we both understand, the two mechanisms slice the universe of data in different ways, which are most useful for attacking different problems. What makes the problem more complex is that different elements have different owners, and one can reasonably say that the UAC-owner can look at the action of a proxy in regard to one of the UAC's requests, but not have the right to examine the proxy's full log. Conversely, taking the intersection of the two questions, a log file format should record at least enough information about a transaction as you would want in a trace facility.
