Hi Darren, all, 

FWIW, you may find some comments at: 

* pdf version: https://github.com/boucadair/IETF-Drafts-Reviews/blob/master/draft-ietf-6man-segment-routing-header-14-rev%20Med.pdf 
* doc version: https://github.com/boucadair/IETF-Drafts-Reviews/raw/master/draft-ietf-6man-segment-routing-header-14-rev%20Med.doc 

I do like the latest version of the spec compared to the versions including a bunch of TLV objects. For example, removing the NSH container and the like seems the right approach. 

There are still some aspects that need to be clarified in the text, e.g.,:
- be explicit that padding objects are mandatory to implement/support.
- whether HMAC is mandatory-to-implement/support?
- what is the use of the HMAC flag?
- why the flag bits are separated from the tag field given that no concrete use is defined for the tag.
- ... 

Thank you. 

Cheers,
Med
