Hi, lets say I have a list 'a' (keyed by n) with a nested list 'b' (keyed by m): list a { key n; leaf n; list b { key m; leaf m; } } I now want to refer to a list element of list 'b' within list 'a'. What is the best way to express this? I could do this: list c { key x; leaf x; leaf aref { type leafref { path /a/n; } } leaf bref { type leafref { path /a/b/m; } } } What is the best way to constrain the leafrefs so that they are forced to point to a 'b' within an 'a' element? Alternatively, I could consider using an instance-identifier: list c { key x; leaf x; leaf bref { type instance-identifier; } } What is the best way to restrict the instance-identifier so that it has to point to a 'b' element? Are there other approaches? I think this is a rather common modeling problem and perhaps we can come up with a best practice pattern for this? If so, I am happy to add it to my pattern collection I-D. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/>
