0070 The <font color=red>PSet default = { ... }</font> parameter, inside the context of a given destination,
0071 specifies that for all types of messages <em>other than those explicitly dealt with by their own
0072 Pset's in this destination</em>, there should be a given limit on number of times this destination
0073 will report messages of the same ID.
0074 <p>
0075 For example, having been assigned a default limit of 10 occurrences and timespan of 180 seconds,
0076 critical.txt would report the first 10 occurrences of a edm::LogError("thisID") message, and the first
0077 10 occurrences of a edm::LogError("thatID") message. After the 10 occurrences, an exponential backoff
0078 kicks in. After 180 seconds of no messages of that type, the count is reset, so that 10 more occurrences
0079 could appear.
0080
0081 <p>
0082 The <font color=red>PSet default = { ... }</font> parameter is optional. If neither a default limit nor
0083 a limit specific to the particular message ID is provided, then that destination will report all messages
0084 of that ID.
