Yes, agreed. In the document, we did not want to cover the various ways
to provide IPv6 support on all possible underlying technologies. We also
wanted to keep it simple and not to go into too many details. The goal
of the text above was to show that when native IPv6 signalling is not
yet enabled on the MPLS network, IPv6 support can still be provided. 
The text can probably be enhanced.

Thank you for your comments.
