Thank you for the work put into this document.

Please find below some non-blocking COMMENT points (but replies would be
appreciated), and some nits.

Thank you to Christian Hopps for his shepherd's write-up (including the WG

I hope that this helps to improve the document,




-- Section 2 --
Any reason why the bits of the 'Flags' field are not reserved (except for the
O-bit) ?  or be in a to-be-created IANA registry? I would expect the default
value for sending them (usually 0) and what to do on the receiving side(s) when
the value is not 0 (usually ignore them). E.g., see the section 7.1

-- Section 3 --
Isn't it obvious that the "Segment Routing Algorithm" is also supported by SRv6
routers ? Consider removing this section ? If you prefer to keep it, then
please use the wording "Segment Routing Algorithm" exactly as in the IANA

-- Section 7.1 (also 7.2 and possibly others) --
The header 'Length' should not be defined as 'variable' as it is probably a
fixed length of 1 octet. Specifying how it is measured and in which units
(octets, 32-bit word, ...) is probably welcome.

-- Section 7.2 --
What is the default value of the "Flags" field?

== NITS ==

-- title-
Should the plural form be used for 'extension' ?

-- Section 1 --
s\topology/algorithm specific\topology/algorithm-specific\ ?

-- Section 13 --
While there is a rather long contributors list, there is no acknowledgement
section. The latter is of course optional but usual. Should the doc shepherd or
last call reviewers be acknowledged ?
