> rule "X" extends "Y" 
> is accepted even if no rule "Y" is available. "X" will be created with local conditions and actions only.
> This is extremely dangerous and very difficult to debug in two cases:
> - rule "Y" exists but is in a different package (not supported)
> - rule "Y*" exists and "Y" is a spelling mistake
