I have been asked to review the above draft as one of the reviewers.

The doc is useful in certain MPLS scenario's as described in the draft. It could be considered to be adopted as a WG doc.

Here are some comments which would make the draft more sound.
1. Describe the behavior for devices that did not implement the additional TLVs. How would they behave.
2. Describe the behavior if the packet length would be exceeded by the Relay Node Address Stack TLV
3. Give an example in the text for the inter-AS and seamless MPLS scenario how the different devices behave with a use case
4. Describe in which scenarios this is applicable: mainly transport MPLS, but not in IP-VPN or L2-VPN scenarios
