Oops
I had to add the fully qualified name for the class... See the bolded text
below...
<event type="pre-update">
<listener class="*GolfHandicapManager.Data.*AuditEventListener,
GolfHandicapManager.Data"/>
</event>
<event type="pre-insert">
<listener class="*GolfHandicapManager.Data.*AuditEventListener,
GolfHandicapManager.Data"/>
</event>
