I have a question about “when” and mandatory objects. It seems to me that the implemented semantics of “when” are really “optional when”, in that the enclosing object can be absent even though it is mandatory and the “when” clause holds true. The RFC could be clearer about this.
Example leaf color { enumeration { enum “blue”; enum “black”; } mandatory true; } container foo { when ../color = ‘blue’; etc. } “foo” is optional due to the presence of the “when” statement even though the object is mandatory (same is true for mandatory leaf, min-elements=1 list etc.). This is considered valid XML for the above <color>blue</color> In my view this makes conditionally variant schemas “loose” in their enforcement (some scenarios can use choice but it doesn’t cover everything). I think that mandatory should be respected for the enclosing objects of a “when” statement. That is, a mandatory object must be present when its “when” clause holds true and a Schematron statement should enforce that. What is the rationale behind the current YANG rules behavior, that the “when” Schematron mapping doesn’t check for presence of the enclosing mandatory object? thanks Mike Rehder “Amdocs’ email platform is based on a third-party, worldwide, cloud-based system.
