Robert, your description of the conflict situation does not match my
understanding.
A new rFC can always update existing RFCs. However, it can't do so
silently. If this document wants to make a change to 8200's rules, it
needs to say so. And explain the benefit. And have the proposal
discussed in 6man.
The current document that has requested working group adoption does not
address these needs.
Yours,
Joel

Dear Ron,
While authors may address your other questions allow me to express an
opinion regarding your observation:
"conflict with RFC 8200 [1] [2]"
As written today RFC 8200 provides rules for insertion and handling of
those extension headers which are enumerated in said RFC and are listed
in IANA IPv6 Extension Header Types registry. SRH is not part of either
of those lists.
It also has been communicated very clearly by 6man chairs and ADs when
RFC8200 was proceeding that any future document can update it when it
defines new types of extension headers therefor I find your reasoning of
"conflict" quite bizarre.
Kind regards,
R.

While I like many things about this draft, I don’t think that it is
ready for adoption. Reasons follow:____
__ __
* Section 4.1 appears to contradict Section 4.3.1 of
draft-ietf-6man-segment-routing-header. In particular, consider
the behavior when Segments Left equals 0.____
* Sections 4.13, 4.14. 4.21.1 and 4.21.2 appear to be in conflict
with RFC 8200 [1] [2].____
* The intent of section 4.19 is unclear.____
* As Adrian points out, the draft extends the semantics of the
IPv6 address. Such a decision may have wide-reaching impact, and
should be socialized with a wider community (6man, INTAREA WG,
V6OPS)____
* The draft appears to be in conflict with
draft-ietf-6man-segment-routing-header regarding how extension
headers after the SRH are processed. According to
draft-ietf-6man-segment-routing-header, subsequent extension
headers are processed out of order, potentially in conflict with
RFC 8200. According to this draft, subsequent extension headers
are ignored.____
__ __
[1] According to RFC 8200, “Each extension header should occur at
most once, except for the Destination Options header, which should
occur at most twice (once before a Routing header and once before
the upper-layer header).”____
__ __
[2] According to RFC 8200, “extension headers must be processed
strictly in the order they appear in the packet” . Sections 4.13
and 4.14 violate this rule by prepending an SRH before the SRH that
is currently being processed.____
