|- is a word that is not allowed in ACE
|- is an error message explaning how to act
This is a simple list of (function) words that are not allowed in ACE. BUG: The question remains if one could be allowed to define such words as content words and use them anyway. In this case, the error message would be misleading. Should we in ACE define a set of words that are not ACE function words and that can not be ACE content words either.
