Clarification Required regarding LSP Encoding Type

["manoj juneja" <manojkumarjuneja@hotmail.com>]

Hi All,
        The draft "draft-ietf-mpls-generalized-signalling-02.txt"
defines different values for LSP encoding type. How does the
implementation of a control plane differ if it receives the LSP encoding 
type packet/SDH/Digital Wrapper/Lamda/Fiber etc.

My understanding is that if the LSP encoding type is either packet/ethernet, 
then label is just a 32 bit integer (as we already have in traditional 
MPLS). But if LSP encoding type is SDH, SONET then the label has to be in 
the form of {S, U, K, L, M} format. If the LSP encoding type is Lamda then 
the label represents the lamda (specific frequency). If LSP encoding type is 
fiber, then label is the fiberId itself.  Please comment on whether my 
understanding is correct or I am overlooking something.
Can u please describe a scenario in which the LSP encoding type
will be used as a "digital wrapper" ?

Please clarify.

Regards,
manoj.
