[netmod] if-feature vs. Identifiers and Their Namespaces

[Robert Varga <[e-mail]>]

Hello,

I have went through RFC7950, but I cannot find the text which would give
answer whether:

feature foo;
feature bar;

container baz {
   if-feature "foo and (not baz)";
}

list baz {
   if-feature "(not foo) and baz";
}

is valid YANG or not. The two statements violate Section 6.1.2, but they
are mutually exlusive when conformance comes into play.

Does compliance (Section 5.6) have any bearing on namespaces (Section
6.1.2)?

Thanks,
Robert
