If the target node is in another module, then nodes added by the augmentation MUST NOT be mandatory nodes

[GoogleCodeExporter]

In Section 7.15. "The augment Statement" of the draft there is a statement:

"If the target node is in another module, then nodes added by the
augmentation MUST NOT be mandatory nodes (see Section 3.1)."

It seems that in the current version of pyang there is no such validation.
See the attached examples. The module ns2 augments the container "c" in the
module ns1 by adding a couple of mandatory nodes. But pyang does not report
these errors.

Why is this CLR needed?

B/c otherwise a client that happily implements an application to configure 
module A
will not work if module B augments A with some mandatory stuff, and the device
supports both A and B.
