A set of AlertRegions will be associated with a specific OutPort. The value associated with the AlertRegion set
is the one contained in the DataEvent being output.

When the value contained in a DataEvent activates an AlertRegion the DataEvent will contain a NumAlert associated to the
AlertRegion along with the time of occurance stored in the lastTrigger. In a condition-based monitoring system, the following DataEvents
from that OutPort will have new values and new times. However, the NumAlert will remain the same while in that region.
This includes the lastTrigger time which may be used as an indicator of how long a particular region has been in effect.

When a Region is first entered it gives the specific DataEvent an "Alert Status". For CBM modules supporting "Alert Status"
functionality, the output can be suppressed to output only when an alert trigger occurs. This mechanism requires one of
the connected type interfaces.

(RegionId, OutPort handle) can be the identifier used by a higher module to control threshold levels via a user
defined ControlVector. Future versions of the standard will begin to create a standard UML/XML form for this control.
