Browser "rendering" is commonly done via ZPT, though this isn't a 
requirement.  For example, you could return html via your action 
handling object.

Often the response to a request will be a response page template, which 
  presumably will have access to the context, request, etc. and the view 
class specified in the browser:page ZCML for that template.  Your 
handling code could pass info via any of these object.

e.g. hard code response params..
request.response.redirect("status.html?status=OK&message="Saved!")

Using ZCML you could add a menu item to the zmi_actions menu, with 
"for=*" and a corresponding browser page for your form.  This won't be 
tied to any "types" (but, will still have a rendering context).
(Look in zope/app/configure.zcml to see how the undo menu is setup).

Keep in mind the menu/actions configuration for X3 is currently very 
basic compared to something like Plone.
