The avalon:name attribute has nothing to do with the logging. These are

It is useful with respect to exception management. If you have
exceptions that are passed from one system to another, it is desirable
to pass information on which a reasonably elegant message can be
generated on a remote system. This message is outside any logging
context and naming strucrture implied by a containment hierachy.
