It cannot cross reference between two yang

[iflove...@gmail.com]

Hi,

I have two yang, aaa and bbb, and I want to bbb refers to aaa.

<aaa.yang>
module aaa {
namespace "urn:test:aaa";
prefix a;

container aaa-settings {
leaf name {
type string {
length "1..63";
}
}
}
}

<bbb.yang>
module bbb {
namespace "urn:test:bbb";
prefix b;

import aaa { prefix a; }

container bbb-settings {
leaf aaa_ref {
type leafref {
path "/a:aaa-settings/a:name";
}
}
}
}

But I can add a aaa_ref even if the a:name is not existed.

Is the bbb.yang right?

Or is there anything I missed?

Thank,
Severa
