Working Group, Deborah,

This errata has been posted four two weeks, with no one speaking
up against it.

We've consulted with the authors, they agree that is is correct.

I think we are ready to approve it.

Deborah,

Can you mark the errata approved.

> 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.
