Hi Tom,

Good catch. We also caught this last week and started formulating the
revised text.

We may strive to rewrite this section a bit, time permitting.

> Question: does the second sentence say anything different from the first

Not really. :) 

> Question: if the MAP node is configured differently, how will other
> nodes be able to synthesize its MAP IPv6 address from the FMR?

Cheers,
Rajiv
