               The locator attribute is used to locate an action 
               within a &lt;Transaction&gt; element.  The value
               of the locator attribute is either a string that
               is equal to the value of the handle attribute
               specified on an  &lt;Insert&gt;, &lt;Update&gt;
               or &lt;Delete&gt; action.  If a value is not 
               specified for the handle attribute then a WFS 
               may employ some other means of locating the 
               action.  For example, the value of the locator
               attribute may be an integer indicating the order
               of the action (i.e. 1=First action, 2=Second action,
               etc.).

               The code attribute may be used to specify an 
               exception code indicating why an action failed.
