in RFC 7950, The last paragraph, section 5.1.1 "Import and Include by
Revision" states:
"If a module is not imported with a specific revision, it is
undefined which revision is used."
But I was wondering if the above text is misleading, since section
5.6.5: "Implementing a Module" has the following two paragraphs:
If a server implements a module A that imports a module C without
specifying the revision date of module C and the server does not
implement C (e.g., if C only defines some typedefs), the server MUST
list module C in the "/modules-state/module" list from
"ietf-yang-library" [RFC7895 <https://tools.ietf.org/html/rfc7895>], and it
MUST set the leaf
"conformance-type" to "import" for this module.
If a server lists a module C in the "/modules-state/module" list from
"ietf-yang-library" and there are other modules Ms listed that import
C without specifying the revision date of module C, the server MUST
use the definitions from the most recent revision of C listed for
modules Ms.
The reason for these rules is that clients need to be able to know
the specific data model structure and types of all leafs and
leaf-lists implemented in a server.
This seems to imply that import without specifying the revision would
mean that the latest revision listed in ietf-yang-library must be the
one that is imported. Is that correct, or am I misinterpreting the
text? Hence, should the last paragraph of section 5.1.1 be deleted?
Thanks,
Rob
