I don't have the JSP spec in front of me to check, but I don't think
<jsp:include> accepts expressions on the "page" attribute.  However,
you could write your own custom tag (or JSF component) that did so,
and then did a RequestDispatcher.include() inside -- that's
essentially what <tiles:insert> does.

Providing ViewController support for subviews is on my TODO list, but
it's not supported yet.  I'm trying to avoid the need for a custom
<f:subview> replacement, but haven't figured out a way to do that yet.

The ViewHandler decoration that Shale uses is not MyFaces specific ...
it should run on any standard JSF implementation.  The decorator
pattern support is mandated by the spec.
