27   *  <ol>

29   *      <li>expressionString - expression String {@link javax.el.Expression#getExpressionString()}</li>

34   *  interface is located in facelets view (line/column)
35   *  and what XML attribute (name/value pair) makes it.

37   *  Also you can think about this type as about ligthweight version of {@link TagAttributeAware}
38   *  for cases, where full TagAttribute instance is not available
