Hello,

In RFC7950 there is a sentence:

A server MUST NOT implement more than one revision of a module.

Considering this is it allowed to mount different versions of a
virtual router on the same YANG server involving different revisions
of the same YAM?

platform
- mounted-vRouter-ver1
- mounted-vRouter-ver12
Yes, that's more or less inevitable.

It might be inevitable, but as I see it, it is expressively forbidden
by YANG. Should we do something about it?
The server advertises which modules it implements in the yang
library. There can not be any module version conflicts here.

With schema mount, the server's "data model schema" is divded into
several disjoint "schema", where each mounted schema is in its own
"mount jail". Within each such "mount jail", there can only be one
implemented version of a module.

BALAZS: I can agree with that, but I did not find text about this in the schema-mount draft. Sorry if I missed it. On the other hand RFC7950 is very explicit.

regards Balazs
