pyang versus pyang --ietf: error discrepancy

[bclaise]

I thought that the "pyang --ietf" was a superset of pyang. However, two of the LMAP YANG data models below produce an error for pyang, but not for pyang --ietf. What is even weirder is that the same error type shows for the third one (ietf-lmap-common@2015-10-28.yang ) for both pyang and pyang --ietf

it is the normal pyang (w/o --ietf) that complains about the imported module. --ietf only reports problems with the module itself.
