[Zope-dev] Eliminating forced HEAD/TITLE/BASE HREF

I need to use Zope output in a server-side include on another machine that's not running Zope. Has anybody come up with a reasonably clean way to suppress the enforced emission of the opening HTML, HEAD, TITLE and BASE HREF tags? It is rather frustrating, given the package's great sophistication otherwise, that one doesn't have control over those odd bits of HTML. I looked at the Python code but it seems to be the usual multilayered marvel and I can't quite see where to put the scalpel. Any assistance appreciated.
