— Aggregation of ProSeIRIContent is an optional feature.

— It may be applied in cases when at a given point in time

— several IRI records are available for delivery to the same LEA destination.

— As a general rule, records created at any event shall be sent

— immediately and not withheld in the DF or MF in order to

— apply aggregation.

— When aggregation is not to be applied,

— ProSeIRIContent needs to be chosen.
