Hi all,

We have updated draft-ietf-ccamp-lsp-dppm into a -05 version.
The only technical change: we included 
draft-shiomoto-ccamp-switch-programming by Kohei Shiomoto and Adrian Farrel 
as a reference. We believe it is a good companion document to the our draft, 
as it clarifies the potential implementation inconsistency of provisioning 
in CP and DP.

Comments are welcome.
