------------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
This could be documented better (or at all), but the correct course of action
is to inject the Request object, check the isXHR() method, and return the
appropriate value (Block or component when XHR is true, null or a page when XHR
is false).
