[rules-users] Collect Function

[Ronald R. DiFrango]

I also realize although the logic is all backwards the using the forall
works as the following:

DetailLine(detailKeyRecNo:keyRecNo != null, lineNumber != null )
forall( RrHeader( keyRecNo != detailKeyRecNo ) )

Not sure which one is better performing or not though.
