Not sure if I ever mentioned this. With an iterate tag, would the
following be possible: [not got jstl to hand so inventing the names]
<c:iterate collection="myPhones" variable="col">
<c:preIterate><p>My phones are<ul></c:preIterate>
<li><c:get name="col"/></li>
<c:postIterate></ul>.</p></c:postIterate>
</c:iterate>
I'm sure I'm doing lots of nasty things. But thought I'd ask.
