title: Angular 9 Accessibility: combine string and binding for arial-label
body: <p>In Angular 9, I have a button to edit a contact in a table of contacts.</p>
  
  <pre><code>   &lt;button class="btn btn-link btn-sm" aria-label="Edit Contact"&gt;
       &lt;i class="icon-mini icon-pencil"&gt;&lt;/i&gt;
     &lt;/button&gt;
  </code></pre>
  
  <p>I obviously can add the <code>aria-label</code> to the icon button to say what it does, "edit contact".  But I'd like to say "Edit Contact Jim Jones", which in this table would be <code>{{contact.full_name}}</code>.</p>
  
  <p>Can this be done?</p>
