[LES:] Thanx - I will correct the text before publishing.

[LES:] Understood - but this should not be of great concern. So long as the 
address used is unique/stable whether it matches the Router ID or not won’t 
affect operation.
Would it have been simpler if we could have said "Use the value in TLV134/140"? 
Absolutely - but another address with the same characteristics will work just 
as well.
