You'll need to wrap the form into a Products.Five.browser.BrowserView.
Overwrite the __call__ method of that to just call the form and return
what it returns.  This is quite similar to how
plone.z3cform.layout.wrap_form works, and in fact, it would be easiest
if you'd write your small wrapper template and pass that as the 'index'
argument to wrap_form.  That template should then probably be included
in plone.z3cform itself.
