This document defines new IPFIX IEs to export measured delay. It is well written with a few nits.

Nits:
Introduction: par. 4 IPIFX -> IPFIX

draft-fz-spring-srv6-alt-mark-10 new release 11 exists 

srhActiveSegmentIPv6 and
srhIPv6ActiveSegment both seem to mean Active SRv6 Segment and also they are the same?

Table 2: R3 and R4 have the same address, not sure if there is an issue there?

Section 5 starts referring to IEs with their IDs with no explanation
