Summary: Ready
--------

Comment:
--------

When I reviewed this for Last Call, I had two general concerns:
1) Is it useful to publish use cases now, at the end of
protocol development?
2) The AD review dated 2017-04-20 pointed out that the
document should be historically consistent.

I'm going to assume that since the AD is bringing the draft
to the IESG, he's now happy on these two points.

Minor issue:
------------

I originally commented that Section 3 doesn't actually mention
any specific requirements for Spring. In conversation with
Stefano:

>> Right, but you don't state any *requirements* for SPRING that result from this case,
>> except the very general statement before section 3.1. Maybe that does translate
>> into specific requirements, but I don't see how.

> the generic requirement is the ability to instantiate source routed paths.
> These source routed paths, in the framework of this draft, are for LFAs.

I still think that Section 3 doesn't identify this requirement.
Maybe it's obvious to one skilled in the art, however. So
I'm going to say "Ready".
