The following steps test most attribute groups that indicate the absence of a finding. This approach differs from the general tests applicable to other attribute groups because of the way in which assertions of absence affect the direction of subsumption. This is discussed in detail in Recording and retrieving absent findings .

  1. Attempt to match each attribute in the predicate - attribute group with an Attribute which has the same name in the candidate - attribute group :
  2. For each of the matched attributes identified in the previous step, compare the value of the attribute in the predicate - attribute group with the value of the same attribute in the candidate - attribute group :
  3. If all the tests above are successful, the predicate - attribute group subsumes the candidate - attribute group :
    • Exit with result true .
