title: How to use transclude without template in Angular directive?
body: <pre><code>&lt;button command="saveCmd"&gt;{{saveText}}&lt;/button&gt;
  </code></pre>
  
  <p>Command directive does not have any template - it's behavioral directive. But I need to use <code>transclude: true</code> to display <code>{{saveText}}</code>. </p>
  
  <p>I could create dummy template like <code>template: "&lt;div ng-transclude&gt;&lt;/div&gt;"</code> but I'm not sure if div inside button is valid html for all browsers. </p>
  
  <p>Also I could use an attribute to define title, for example <code>&lt;button title="saveText"...</code> But my question is about ng-transclude without template. Is it possible? </p>
  
  <p>Thanks in advance. </p>
  
  <p><strong>Update:</strong></p>
  
  <p>A new 'isolate' scope <code>scope: {}</code> inside directive is a reason why {{saveText}} is not persisted by default. </p>
