Where the Required attribute is 'No' then a course that does not meet that criteria may be included in the set. In all cases, where the criteria has been included in the request, the comparable trait and its value will be returned, along with the basic course information and identification. The message may also include Warnings from business processing rules or Errors if the request did not succeed.
