title: create and label a textblock in word using c#
body: <p>I am trying to write an Add-In (VSTO) for Word to add some software requirement-management capabilities to it.</p>
  
  <p>assume a Requirement would follow this convention: </p>
  
  <pre><code>[REQ_&lt;nr&gt;]  Specification item title  
  ⌈ Specification item description. ⌋ (REQ_&lt;nr1&gt;, REQ_&lt;nr2&gt;)
  </code></pre>
  
  <p>Is there anyway to declare this block and name it so, that you can later find all Requriements using OpenXML and c#?</p>
  
  <p>thanks</p>
