Ron,

That sentence is there on purpose. RFC8200:
   IPv6 nodes must accept and attempt to process extension headers in
   any order and occurring any number of times in the same packet

I will update that sentence in the next revision of the draft to make it more formal and include the normative reference:
“As per [RFC8200], multiple occurrences of the SRH might be present in the same IPv6 header.”

Cheers,
Pablo.

Authors,

In Section 2 of draft-ietf-spring-srv6-network-programming-04, you say:

“SRH: Segment Routing Header as defined in  [I-D.ietf-6man-segment-routing-header].  We assume that the SRH may be present multiple times inside each packet.”

Did you mean to remove the final sentence?

                                     Ron
