+ *  <a href='https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind'>MDC's bind() documentation</a> and

+ *  for a complete explanation.
+ *
+ *  This extension already exists in some browsers (namely, Firefox 3), but
+ *  we provide it to support those that don't.
+ *
+ *  Parameters:
+ *    (Object) obj - The object that will become 'this' in the bound function.
+ *    (Object) argN - An option argument that will be prepended to the 
+ *      arguments given for the function call

+ *  >     <example/>
+ *  >   </query>
+ *  > </iq>
+ *  The corresponding DOM manipulations to get a similar fragment would be

+ *  Since adding children makes new operations operate on the child, up()
