Extended attributes are custom fields that are present on cases and alerts. They are populated and processed in a similar way to attributes, but are defined and stored differently.

Whereas attributes are an intrinsic part of the case and alert structure, extended attributes are defined in a configuration file, flags.xml, which is found in the ..\oedq_local_home\casemanagement directory.

The default installation defines two extended attributes:

• Escalation - a Boolean attribute which, if set to true, indicates that the case or alert is in an 'escalated' state.

• PriorityScore - a numeric attribute which is intended to be used to hold the priority score for an alert, as generated by the match processor.
