DISCUSS:

Section 9.  The primary impact of the manipulating writable nodes appears to be
characterized as DoS.  Don’t the possible consequences also include the ability
to leak traffic outside the trusted domain or to route traffic through
arbitrary paths of the attackers choosing potentially enable on-path inspection
or manipulation of traffic; or avoidance of security controls?

COMMENT:
----------------------------------------------------------------------

** Section 9.  Thanks for using the templated YANG Security Considerations.  A
nit on the references s/[RFC6536]/[RFC8341]/

** Section 9.  The following caution around readable nodes didn’t parse for me.
 Was the intent as follows:

OLD
The exposure of both local
   bindings and SID database will exposure segment routing paths that
   may be attacked.

NEW
The exposure of either the local bindings or SID database would provide an
attacker the segment routing paths and related topology information.
