DISCUSS:
----------------------------------------------------------------------

It looks like the description of filter-failure-hint in
modify-subscription-stream-error-info needs the same treatment that
establish-subscription-stream-error-info  received.

COMMENT:

[original comment section replaced]

In the updated security considerations:

   The replay mechanisms described in Sections Section 2.4.2.1 and
   Section 2.5.6 provides access to historical event records.  By
   design, the access control model that protects these records could
   enable subscribers to view data to which they were not authorized at
   the time of collection.

Looks like there's some xml2rfc redundancy ("Sections Section").

   o  "excluded-event-records": leaf can provide information about
      filtered event records.  A network operator should have
      permissions to know about such filtering.  Improper configuration
      could provide a receiver with information leakage consisting of
      the dropping of event records.

In mail I had proposed "Improper configuration could allow a receiver to learn
that event records were dropped due to an ACL when the existence of that ACL
would otherwise be transparent."; repeating it here just in case it got missed
(but this  remains the non-blocking comment section).
