Hi chairs/authors,
  Thank you for your hard work on this important document. I have reviewed draft-ietf-spring-srv6-security-14 and I think it is ready to progress further in the IETF process. I do have some minor comments that you may want to address

* Section 6.1.

This sentence is missing a verb and does not read right. Suggest rewording to

OLD:
While it is possible for packet manipulation and processing attacks against all the fields of the IPv6 header and its extension headers, this document limits itself to the IPv6 header and the SRH.

NEW:
While packet manipulation and processing attacks are possible against all the fields of the IPv6 header and its extension headers, this document limits itself to attacks on the IPv6 header and the SRH.

* Section 6.2.1.1.

This sentence is a bit confusing. Suggest rewording 

OLD:
However, it facilitates more complex on-path attacks by redirecting traffic to another node that the attacker has access to with more processing resources.

NEW:
However, it facilitates more complex on-path attacks by redirecting traffic to another node, with more processing resources, that the attacker has access to.

* Section 8.1.

Not sure what "take care of” means here? I would suggest using “handle” or “inspect” depending on what you intend to say here.

Regards
Suresh
