[netmod] Query about augmenting module from submodule in YANG 1.0

["Ivory, William" <[e-mail]>]

Hi,

We're trying to solve a modularity problem with a YANG module by splitting it into submodules and augmenting the parent module from each submodule.  However, despite the wording below in YANG 1.0 section 7.15, we've found a couple of threads online with comments suggesting it's only allowed in YANG 1.1?  Would appreciate clarification.

RFC 6020 section 7.15 suggests it is allowed:


'
   The "augment" statement allows a module or submodule to add to the
   schema tree defined in an external module, or the current module and
   its submodules, and to add to the nodes from a grouping in a "uses"
   statement.
'

Versus online comments here: https://www.ietf.org/mail-archive/web/netmod/current/msg15418.html

This isn't possible in YANG 1.0 but will be possible in 1.1. However, in the present case the definition being augmented from the submodule is arguably in a different module.
