[Med] I prefer to maintain the current structure as it adheres with this part 
from 7950  

   As a shorthand, the "case" statement can be omitted if the branch
   contains a single "anydata", "anyxml", "choice", "container", "leaf",
   "list", or "leaf-list" statement.  In this case, the case node still
   exists in the schema tree, and its identifier is the same as the
   identifier of the child node.

I made this change to remind this is still part of the choice: 

OLD: 
                container ldp-or-l2tp {
                  description
                    "Container for LDP or L2TP-signaled PWs. ";
NEW:
                container ldp-or-l2tp {
                  description
                    "Container for LDP or L2TP-signaled PWs 
                     choice.";
