SBVR — Page: 296

Problem Description Under the list of Operative Rule Keywords in the first paragraph of the page, the following is listed: << only ... often as in 'only if' ... rule keyword >> The actual full rule keyword is "may ... only". "Only" may not be used without "may". "Only" produces a restricted permissive form of a rule; "may" must be present to indicate that permission is being restricted. (Note: the corresponding structural rule keyword is "can ... only", which is given correctly in the list for the next paragraph on that same page.) Proposed Solution: 1. Change << only ... often as in 'only if' ... rule keyword >> to: << may ... only ... often as in 'only if' ... rule keyword >> 2. In the third paragraph of text, item 1, which reads: ‘Should’ may be used in place of ‘must’ in expressing a business rule only if one of the following is true: • The business rule does not have an enforcement level. • The business rule has an enforcement level, and that enforcement level is consistent with the English sense of ‘should’. ... change the very first "may" (second word in the extracted text) to styled text for rule keyword.
