<p>
Provide a way for Faces applications to register an <code>ELContextListener</code> that will be notified on
creation of <code>ELContext</code> instances.
<p>

<p>
An implementation is provided that throws <code>UnsupportedOperationException</code> so that users that decorate
the <code>Application</code> continue to work.
