A general expression raises a question about the range of persons or instances it includes. An unrestricted expression raises a different question: whether an additional feature or qualification can be attached to what is mentioned. Calling both situations simply “unrestricted” erases an important distinction.
In a hypothetical rule “Every registered person must notify,” removing one class concerns specification. In “Appoint one registered person,” adding “adult” concerns an additional qualification. Each requires legitimate grounds, but the interpretive operation differs.
Error: Treating one proven exclusion as a license to add new conditions to any text. Correction: Identify whether the original wording is general over members or unrestricted as to a relevant attribute before selecting the appropriate rule.
