Following our previous liaisons, we would like to update you on the progress of
the MEF IP Service Attributes project. A new Approved Draft of our
specification for IP Service Attributes for Subscriber Services is available,
which can be accessed as described below. Note that a corresponding
specification for IP Service Attributes for Operator Services is in progress
but an Approved Draft is not yet available.

In the course of our work, we have reviewed some of the internet drafts from
the L3SM working group that preceded publication of RFC 8049 ("Yang Data Model
for L3VPN Service Delivery"), and we used this as input to our specification.
Now that RFC 8049 is published, we intend to review it again to ensure our work
remains aligned. We would appreciate your review of our Approved Draft, and in
particular any assistance you can give in identifying areas where it may
conflict or be otherwise misaligned with RFC 8049.

Note that the scope of the current IP Service Attributes project does not
include definition of a yang module; however, we expect that a future project
will include specification of a yang module based on the service attributes
defined in this document. It is our hope that such a module can be defined as
an augment of the module defined in RFC 8049.
