Lada, It sounds like you are proposing in (1) a fairly significant change in the direction of the draft and in (2) a basic approach that has been rejectected by the WG multiple times. FWIW there are drafts already with the iesg that will need to be returned to their WGs if either change is ma

Hi, unfortunately, using an action for querying embedded YANG library data (needed for the "inline" case of schema mount) doesn't work either because now under NMDA actions can be used only on instances in the datastore. However, a good alternative seems to be a metadata annotation along the lin

Hi, the following text in sec. 3.2 of schema-mount-08 is wrong for traditional datastores, and even more so for NDMA: In case 1 ["inline"], the mounted schema is determined at run time: every instance of the mount point that exists in the parent tree MUST contain a copy of YANG library d
