# This is a fix for the interaction of the gem `rails3_acts_as_dag` and the ActiveRecord
# presence validation. 
# The gem recommends to use the method `validates_uniqueness_of_without_deleted`,
# but since do not have access to the `acts-as-dag` validation declaration,
# this is not an option here.
# This, this fix adds a corresponding scope to the standard validation method.
