Hi WG,

We have some pending issues with draft-ietf-pce-binding-label-sid, as part
of the WGLC, that needs more inputs from the WG.

(1) Use of an explicit R flag to remove TE-PATH-BINDING TLV
Olivier and others suggest using a new R flag to explicitly remove
TE-PATH-BINDING. The current text requires all the TE-PATH-BINDING TLVs
that apply from that point on to be encoded.

A new R flag would have an impact on any existing
implementation/deployment. Please confirm on the list (or to the chairs
directly) if you object to the suggested change.

(2) Use of the term "Binding Label/SID"
Tom asked to use binding value instead.
As per authors
- Binding value is the term when referring to the specified value in the TLV
- binding label/SID is used in the generic sense

We also found label/SID or SID/label terms to be in use in multiple RFCs -
RFC 8403, RFC 8660, RFC 8664, RFC 8665.

Is the WG happy with the continued use of the term "binding label/SID"?

(3) Flags related to SR Policy
Adrian suggested removing them. There was no objection to this [1]; authors
are requested to act on this.

Please provide your inputs by 13th April, so that we can make progress with
this I-D. Working copy and Diff can be found at [2] and [3].

Thanks!
Dhruv & Julien
