Status: Verified
Type: Editorial

Section: 5.1

Original Text
-------------
In the case of an SRv6, the SR Binding SID sub-TLV does not have the
ability to signal the SRv6 Endpoint behavior [RFC8986] or the
structure of the SID. Therefore, the SR Binding SID sub-TLV SHOULD
NOT be used for the advertisement of an SRv6 Binding SID. Instead,
the SRv6 Binding SID TLV defined in Section 5.2 SHOULD be used for
the signaling of an SRv6 Binding SID. The use of the SR Binding SID
sub-TLV for advertisement of the SRv6 Binding SID has been
deprecated, and it is documented here only for backward compatibility
with implementations that followed early draft versions of this
specification.

Notes
-----
The incorrect term `SR Binding SID sub-TLV' appears three times in the last paragraph of Section 5.1. The correct term is `SR Binding SID TLV'.
