title: How to refine a leaf's range in YANG model?
body: <p>I have a grouping like -</p>
  
  <pre><code>  grouping threshold-value-grouping {
      container threshold-value {
        description "Threshold value";
        leaf upper-limit-val {
          description
            "Upper limit";
          type uint32 {
            range "1..60000";
          }
        }
        leaf lower-limit-val {
          description
            "Lower limit";
          type uint32 {
            range "1..60000";
          }
        }
      }
    }
  </code></pre>
  
  <p>And i want to reuse this grouping at multiple places.
  But when used at different places, the range of the leaves vary.</p>
  
  <p>So i am wondering how can I use the <em>refine</em> statement to achieve?
  Or is there any better way to address this issue?</p>
