The examples should use documentation IP addresses and not 10/8.

The YANG module has a lot of 'must'.  Should they be MUST with a 
suitable reference to the BCP at the start of the module?  I expect that 
an AD will raise this:-(

I note the wide use of i.e. and e.g. which makes me think the authors 
are comfortable with those abbreviations but I wonder about the two 
'e.g.' in the YANG  module 'requested-info' and 'requested-state'.  Are 
they really e.g.?  No need to change if they are.

'requested-info' is a bit awkward. 'information' singular, 'metrics' 
plural', 'is' singular.  Perhaps
'This grouping defines the information that is requested (e.g. metrics)

'returning path srlgs'
probably worth expanding srlg here in the YANG module

'if also the tunnel name is reported'
perhaps
'if the tunnel name is also reported'

What is the difference between
request-id uint32
and
request-id-number uint32
Seems confusing?

In a number of places, thie I-D says that it contains RPC but it does 
not!  It augments the RPC in yang-te which I think a distinction worth 
making e.g. with
'This document provides a mechanism to [request path computation etc] by 
augmenting the RPC in RFC YYYY'
