That's hard?  ;) Actually, your second way is probably the prefered
'Zope' way to do it.  One quick impovement I can see is that you don't
need the 'name=' in the if tag:

<!--#if section-->

Will do what you want. The #with tag comes in very handy when you are
nesting objects within object.  In some applications, In some
applications, I've had four or five levels of #with nesting.  Any more
than that, however, would mean that the problem probably needs to be
decomposed some more.
