Minor comment: The boilerplate in Section 2 needs to be updated to something like this (note the new BCP 14 reference):
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. I think the document is ready to go with this fix. Scott _______________________________________________ regext mailing list regext@ietf.org https://www.ietf.org/mailman/listinfo/regext
