Suresh,
You have brought up this issue on the ospf mailing list a couple
of times and as such the topic has been addressed on the list.
Here is pointer to an email from John Moy (circa July 2001)
http://discuss.microsoft.com/SCRIPTS/WA-MSD.EXE?A2=ind0107&L=OSPF&D=0&I=-3&P=15162
and another more recent one from me in response to your email on your
alternate-te proposal

Best,
--rohit.

::The draft is a solution to providing TE within an OSPF area.
::The draft has serious scalability limitations in
::extending this to inter-area and mixed networks (with TE and
::non-TE nodes). Please see my comments below. I would not
::recommend using this draft as the basis for building further
::TE-extensions to inter-area and mixed networks.
::
::The draft apparently evolved over time with no requirements
::document to guide it. The vendors and implementors behind the
::draft may have been guided by different set of requirements
::and motivations, such as having some working code. Unfortunately,
::this ad-hoc approach has a cost. Any new requirements are having
::to be met in a reactive mode and having to be provided as fixes
::on top of this "working" code. This is not right and doesnt bode
::well for the future of the protocol.
