Hi Michal, submodule stuff was considerably simplified in draft-ietf-netmod-rfc6020bis, I think it would be better to use the new logic everywhere. Essentially, in YANG 1.1 includes are only effective in the main module, and the result is the same as if the submodule definition were placed in the main module, so they can be used in the main module and all submodules without further includes.
