      * @param root
 33  
      *            the component that is the source of properties or messages (or etc.). When the

      * @param bindingDescription
 36  
      *            The {@link IBinding#getDescription() description} of the binding.
 37  
      * @param expression
 38  
      *            The expression used to get (or update) a value. The interpretation of this
 39  
      *            expression is determined by the type of {@link IBinding} created by this factory.
 40  
      *            In some cases, it is simple the name of an object contained by the root component.
 41  
      *            For the common "ognl:" binding prefix, it is an OGNL expression to be evaluated on
 42  
      *            the root object.
 43  
      * @param location
 44  
      *            The location of the binding, used to report any errors related to the binding, or
 45  
      *            to the component parameter the binding is bound to.
 46  
      *
 47  
      * @return A {@link IBinding} instance for the specific expression given.
