Current Version - Under Revision

The following step tests most attribute groups. However, a modified approach (see 7.8.2.4.5.2.2.2 Testing a context attribute group with absent finding) is required in the case of attribute groups that indicate the absence of a finding.

  1. Test that each attribute in the predicate - attribute group subsumes at least one attribute in the candidate - attribute group :
  2. If all attributes in the group pass this test, the predicate - attribute group subsumes the candidate - attribute group :
    • Exit with result true .
