[netmod] YANG 'must' Xpaths, predicates and wildcards

[Sterne, Jason (Nokia - CA/Ottawa)]

Hi all,

I'm pretty sure that this xpath (e.g. in a must statement) isn't correct:

              (A) ../container-a/list-b[name=*]/some-leaf

and should just be this instead:

              (B) ../container-a/list-b/some-leaf

Or is the * an allowable wildcard for a key value in a predicate ?

I also had a question about whether the following "must" correctly checks that 
at least one entry exists in a-list.

  container c1 {
    leaf foo {
      must "a-list";
      type uint16;
    }
    list a-list {
      key "entry";
      leaf entry {
        type uint16;
      }
      leaf another-entry {
        type uint32;
      }
    }
  }

I think I could also replace that must with the following:
      must "count(a-list) > 1";
but does must "a-list"; achieve the same thing ?

Rgds,
Jason
