I found is pretty easy to read, and have a couple of very minor (editorial) comments: Nit level comments: (1) p 6, sec 3.1. PSID for Performance Measurement PSID can also be used for In-situ OAM[RFC9197] for SR-MPLS to identify the SR Path associated with the in-situ data fields in the data packets on the egress node. PSID can also be used for In-band PM for SR-MPLS to identify the SR Path associated with the collected performance metrics. Just cosmetic, but given the repetition, perhaps put the last 3 sentences in this section into a list, e.g., starting with "PSID can also be used:" (2) p 7, sec 3.4. Nesting of PSIDs Binding SID (BSID) [RFC8402] can be used for SID list compression. With BSID, an end-to-end SR path in a trusted domain can be split into several sub-paths, each sub-path is identified by a BSID. Then an end-to-end SR path can be identified by a list of BSIDs, therefore, it can provide better scalability. BSID and PSID can be combined to achieve both sub-path and end-to-end path monitoring. A reference model for such a combination in (Figure 2) shows an end-to-end path (A->D) in a trusted domain that spans three sub-domains (Access, Aggregation and Core domain) and consists of three sub-paths, one in each sub-domain (sub-path (A->B), sub-path (B->C) and sub-path (C->D)). Each sub-path is associated with a BSID and a s-PSID. As a minor nit, s-PSID is used above, but not defined until the following paragraph.
