title: DevExpress XtraEditors TextEdit mask
body: <p>I have a TextEdit and need to limit its input to the following type of formats:</p>
  
  <ul>
  <li>00.000</li>
  <li>0.000</li>
  <li>00.00</li>
  <li>0.00</li>
  <li>...</li>
  </ul>
  
  <p>There can be up to 3 decimal places. Integer part is not required. </p>
  
  <p>The closest thing I've found is <code>MaskType = Numeric</code> with <code>###.###</code> mask. However, this doesn't accept all zeros, which is a requirement.</p>
  
  <p>Any suggestions?</p>
  
  <p>ADD: I'm thinking of <code>0{0,3}\.0{0,3}</code> with <code>MaskType = RegEx</code>. Is it a suitable choice? </p>
