Section 3.5 says:
RFC 3811 [RFC3811] defines the textual conventions for MPLS. These lack support for IPv6 in defining MplsExtendedTunnelId and MplsLsrIdentifier. These textual conventions are used in the MPLS-TE MIB specification [RFC3812], the GMPLS-TE MIB specification [RFC4802] and the FRR extension [RFC6445]. "Definitions of Textual Conventions (TCs) for Multiprotocol Label Switching (MPLS) Management" [MPLS-TC] tries to resolve this gap by marking this textual convention as obsolete.
It should say:
RFC 3811 [RFC3811] defines the textual conventions for MPLS. These lack support for IPv6 in defining MplsExtendedTunnelId. This textual conventions is used in the MPLS-TE MIB specification [RFC3812], the GMPLS-TE MIB specification [RFC4802], and the FRR extension [RFC6445].

Notes:
Section 3.5 comments about MplsLsrIdentifier.
It says that RFC 3811 "lack[s] support for IPv6 in defining MplsExtendedTunnelId and MplsLsrIdentifier." It also says that "[MPLS-TC] tries to resolve this gap by marking this textual convention as obsolete."
Note that the second quote refers to just one TC.
Looking at 3811, 5036, and (most importantly) 7552, it seems to me that the LSR Identifier is *always* a 32 bit quantity regardless of whether the LDP system is v4-only, v4/v6, or v6-only.
Furthermore, draft-manral-mpls-rfc3811bis (i.e., [MPLS-TC]) clearly shows no
change to MplsLsrIdentifier while marking MplsExtendedTunnelId as obsolete.
Notwithstanding that draft-manral-mpls-rfc3811bis appears to have been abandoned in state "candidate for WG adoption", it looks to me that RFC 7439 has an error we could call a typo.
