AA>--------> I agree...in fact I also absolutely agree that LSP segment
end points do NOT have to be domain boundaries. In fact there could be
other reasons for creating LSP segments spanning a bunch of nodes...one
application that has also been refered to in the document, say P2MP, for
preventing legacy LSRs from being in the path of P2MP tunnels.
