title: Watson conversation: Regexp as entity
body: <p>At a watson conversation I added a regular expression as entity: </p>
  
  <blockquote>
    <p>(e.g. @LimitLiteral :
    (?i)(\d+(\,|.)\d*\s*[^,.;]<em>\w</em>\s*[^,.;]limit)|(limit\s*\d+(.|,)<em>\d</em>).</p>
  </blockquote>
  
  <p>Inside this regexp you can find the constant <code>limit</code>. Is it possible to replace this constant <code>limit</code> with another entity?</p>
  
  <blockquote>
    <p>(e.g. @limit , Limit, maximum , max, not more ..., less)</p>
  </blockquote>
  
  <p>The advantage is that if possible the regexp can be maintained by adding a new value for the entity <code>@Limit</code></p>
  
  <p>thx</p>
