## Comments

* "typedef protocol-number {
               If IPv6 extension headers are present, then the
       protocol number type represents the upper layer protocol
       number, i.e., the number of the last 'next header' field
       of the IPv6 extension headers."

  Surely since this can represent all values of the Next Header field this
  _could_ indicate the value of an IPv6 Extension Header?

  It seems to me that we should just say this is the value of the
  protocol/next header field wherever this numberspace is indicated, and
  that in some contexts extension headers might be skipped over and the
  ultimate next header value is what is meant in this field.

  This should be called out on a case-by-case basis, though, I would expect
  (i.e. wherever this type is used).

* ipv[46]-address-no-zone

  Why are these patterns so much more permissive than the non-zone parts
  of the address patterns?  Why not just copy the address pattern text and
  leave off the %<zone> pattern chunk?

* email-address

  This pattern seems overly permissive.  It appears to permit the RFC 5322
  S3.2.3 "specials" that are not part of "dot-atom".

  I'm no SMTP expert, but it seems like at least excluding the @ special
  might help?  E.g.

      [^@]+@[^@]+

  or something.
