A changes link onto a drafted clause was refused, so records that really
change such a rule could only cite it (ADR 0294, 0301, 0320); and return
renumbered ADR 0281's clauses, pointing other records' links at other
clauses. The changed drafted clause keeps its number and stays unserved;
return refuses a record whose clauses another record changed or links by
number. Issue 494, ADR 0321.
