Hi WG, Authors,

I support adoption.

Looking forward to changes as per the discussion in the other thread
started by Joel. I found a few things that can increase the
readability of the document.

Minor
- The document doesn't use normative keywords of RFC 2119 (RFC 2119 is
in reference somehow still). I am wondering if section 3 and 4 could
use them esp section 4.
- Section 6, I feel we should at least add a reference to Section 8.1
of RFC 8402 [ https://tools.ietf.org/html/rfc8402#section-8.1 ] to
provide a helpful pointer. Can we add some text regarding the context
labels - that they do not impose any security issues with a suitable
reference (provided that is true :)?
- Can we expand "externally visible forwarding behavior", the
reference to draft-bashandy-rtgwg-segment-routing-ti-lfa but I don't
see that term being used there
- Section 5 could use an example to describe the concept clearly

Nits
- Expand sids in abstract
- Expand SRGB on first use
- Should we state it clearly that this document is applicable for SR-MPLS only!
- Suggest to use RFC 8402 notations for the all sids: Node-SIDs,
Adj-SIDs, BSIDs instead of node-sids, adjacency-sids, binding-sids
- Section 2, not sure about "SPRING enabled on each node"
- Section tile for 2.1 and 2.3: I am not sure about the terms
"node-sid explicit paths" and "adj-sid explicit paths" where the later
is actually a mix of node-sids and adj-sids. Perhaps rename them as -
section 2.1 to "Node protection for explicit paths with Node-SIDs" and
2.3 to "Node-protection for explicit paths with Adj-SIDs"?
- Figures, add a legend stating what does the values "10", "30", "60"
on the links mean - it is clear that it is cost, but would be good to
be explicit.

Thanks!
Dhruv
