[rules-users] Cannot recreate a rule or package in BRMS after archiving

Is there a way of really deleting a rule or package in the BRMS? If you archive a rule or package to delete it then you cannot create a new rule or package with the same name as the archived assets - you get an error saying the rule or package already exists! The workaround I'm using at the moment is to rename a package or rule before archiving it. This seems to allow you to create a new rule/package with the same name as the original rule/package - but it isn't nice or intuitive. Thanks Shahad
