Better. However, *if* we are going to hit the text here turn what was a set of 
loose and unbounded examples into a list of specific references, I'd like to go 
ahead and add L2TPv3 as an example of "any other sort of tunnel which can carry 
MPLS packets" and include a reference to draft-townsley-l2tpv3-mpls-01.txt. For 
consistency, we would need to reference your upcoming MPLS over IPsec 
encapsulation draft as well. I find it arbitrary to reference some examples and 
not others.

I'm also fine with just leaving the text as is.
