Hi Dhruv, I agree that pce sending down binding SID should be in the binding SID document, however I have some concerns regarding some of the text that requires PCECC capability exchange in order to allocate the value and erroring otherwise for a PCE-INIT. While the binding SID document is independent of SR Policy, one of its key usage is for SR Policy Candidate path. If a user wants to manually program an SR Policy CP and define a specific BSID and deploy it via PCEP PCE-INIT, I do not think there should be a requirement on PCECC capabilities to do so. While PCEP is not BGP of course, I can manually configure an SR Policy Candidate path with a BSID and inject with BGP without any pre-negotiations. This applies to Replication Segment as well. The BSID needs to be valid in SRLB, not necessarily a valid CCI related value?
Thanks!

Julien and I agree. Also, it makes sense to move the new P-flag in the LSP object here (from path segment WG I-D [4]).
