* <p>
* The <code><o:validateAll></code> validates if ALL of the given {@link UIInput} components have been filled out.
* One could of course also just put <code>required="true"</code> on all of those {@link UIInput} components, but
* sometimes it's desireable to invalidate all of those fields and/or to have just only one message for it, which isn't
* possible with the standard Faces API.
* <p>
* The default message is
* <blockquote>{0}: Please fill out all of those fields</blockquote>

* For general usage instructions, refer {@link ValidateMultipleFields} documentation.
