I'm pretty sure that that same section shows subclassing to override  
setAttribute.  My cutpaste stopped at the spot.

If the wrapper has two methods, getMedium and getVerbose, then you  
can have templates say:

$mydate.medium$
$mydate.verbose$

The first calls getMedium() on the wrapper which formats the data  
held in that object.

Does that help?
