Hi,

Is it possible to define a generic notification in one yang model and the augment on more data conditionally?

the thing I’m trying to achieve is to have a leaf ref in the notification that references different parts of our yang models depending on some data in the notification.

I have

notification general-notification{  
leaf name {…}  
//some general data  
}

[//foo.yang](https://foo.yang)  
augment “general-notification”{  
when “name = ‘foo’”{  
leaf index{  
type leafref { path “somewhere/foo” }  
}  
// add more stuff?  
}  
}

[//bar.yang](https://bar.yang)  
augment “general-notification”{  
when “name = ‘bar’”{  
leaf index{  
type leafref { path “somewhereelse/bar” }  
}  
// add more stuff?  
}  
}

When I populate the data in the “struct confd\_cs\_node” I see the namespaces but I don’t know which one of the “index” noeds to populate.

Can I see the “when” condition in runtime soo I can populate the correct index node without duplicate the when logic in code?
