A general expression from which some members have been excluded.
Suppose a text apparently applies to many members of a class; another valid, specific proof states a different rule for a defined subset. The first text remains general in form, but the actual reach of its ruling has been reduced.
The components are:
1. General wording that includes a class.
2. A valid specifying proof that removes a subset.
3. The remaining class still governed by the general rule.
Preference, speculation and unsupported exceptions are not legal specification. A recognized proof is needed.
