title: How to guarantee custom directive is the only one actually compiled on an element?
body: <p>Is there a way to guarantee that a directive is the only one actually compiled on an element?</p>
  
  <pre><code>&lt;div directive-one ng-include="test.html" some-other-directive&gt;&lt;/div&gt;
  </code></pre>
  
  <p>If I want directive-one to be the only one actually compiled, is there a way to guarantee that?</p>
  
  <p>I assume </p>
  
  <pre><code>terminal: true,
  priority:  ???
  </code></pre>
  
  <p>Is part of the answer (if it can be done).  If it can't be guaranteed, are there any conventions or generally accepted best practices around setting priority values?</p>
