I do not understand the intention behind text in RFC 7950, however. My clarification request was aimed at RFC 7950 authors and whether a revision like this could be considered as not changing the semantics of the original identity definition because: Otherwise, if the semantics of any previous definition are changed (i.e., if a non-editorial change is made to any definition other than those specifically allowed above), then this MUST be achieved by a new definition with a new identifier. So, RFC authors: Is "NEWB:bar" definition semantically equivalent to "OLD:bar" definition?
