* Editorial nit - it's worth a comment as it's either a pretty noticeable typo or I'm pretty confused.

In Figure 1, should the label "Aggreg. Node" actually read "Aggreg. Network"?

* In section 4.1, second bullet list: the sentence
      This MUST allow
      to retrieve statistics and alarms (e.g. via SNMP) about the
is missing some words

* RFC 2119 terminology is not uniformly capitalized; for example, in section 4.2:

   o  The ANCP MUST support providing multicast conditional access
      information to Access Ports on an Access Node, using Black, Grey
      and White lists.

   o  The ANCP MUST support binding a particular Black, Grey and White
      List to a given Access Port.

   o  Upon receiving a join to a multicast flow which matches the Grey
      List the ANCP MUST allow the AN to query the NAS to request an
      admission decision for replicating that multicast flow to a
      particular Access Port.

   o  The ANCP MUST allow the NAS to send an admission decision to the
      AN indicating whether or not a multicast flow may be replicated to
      a particular Access Port.

   o  The ANCP must allow the NAS to indicate to the AN whether or not
      Admission Control is needed for some multicast flows on a given
      Access Port and where needed whether or not the Access Node is
      authorized to perform Admission Control itself (i.e. whether or
      not AN Bandwidth Delegation applies).

   o  In case of Admission Control without AN Bandwidth Delegation, the
      ANCP must allow the NAS to reply to a query from the AN indicating
      whether or not a multicast flow may be replicated to a particular
      Access Port.

   o  In case of Admission Control with AN Bandwidth Delegation, the
      ANCP must allow the NAS to delegate a certain amount of bandwidth
      to the AN for a given Access Port for multicast services only.

* Section 4.7.8: expand acronym "LAC"

More minor comments: 

Section 3.2 should expand or explain OPEX

I have no idea what an "element management interface" is

Not sure how the shutdown notification requirement is justified
