ASR9K IOS-XR 5.3.0 Release Notes:
IPv6 Support in MPLS LDP: Starting from release 5.3.0, support for native MPLS LDP over IPv6 is enabled to continue providing existing services seamlessly while enabling new ones. The attributes and capabilities of the existing MPLS LDP have been extended to be IPv6 aware.
This is based off the -12 draft, that LDP over v6 draft has seen a lot of contention for various reasons.

If you have CCO access you can download the 5.3.0 XRv VMs and play around with it.
Getting IPv6 support in LDP is one thing. This is one document that we need to keep track to know what MPLS applications currently running off of LDPv4 still need to be ported to run over LDPv6: http://tools.ietf.org/html/draft-george-mpls-ipv6-only-gap-04 Mark.
