0070 Each destination can (in addition to limits by message ID) be configured to
0071 react to only some limited number of messages of a specified severity level.
0072 For example, detailedInfo.txt would react to only the first 100 messages
0073 issued via edm::LogWarning(...), and the first 100 issued via
0074 edm::LogError(...), with exponential backoff thereafter.  (Typically, one might
0075 limit the number of INFO or WARNING messages and let all the ERROR messages
0076 emerge.)
0077 <p>
0078 A message can be ignored because the limit for that severity is exceeded, or
0079 because the limit for that ID is exceeded.
0080 <p>
0081 Establishing limits by severity level is always optional.
