Ketan, We also wanted to point out that we lowercased “locator” in the following sentences in both documents per your guidance; for consistency, we also lowercased for “function” and “argument”. Let us know any concerns. Original (RFC-to-be 9513): An SRv6 Segment Identifier (SID) is 128 bits and consists of Locator, Function, and Argument parts as described in [RFC8986]. Original (RFC-to-be 9514): As specified in [RFC8986], an SRv6 SID comprises Locator, Function and Argument parts. Current (RFC-to-be 9513): An SRv6 SID is 128 bits and consists of locator, function, and argument parts as described in [RFC8986]. Current (RFC-to-be 9514): As specified in [RFC8986], an SRv6 SID comprises locator, function, and argument parts.

Is one form preferred? Both documents use the capitalized form when prefaced with “SRv6”; that is, both use "SRv6 Locator”. However, when not prefaced with “SRv6”, the capitalization varies.
