BFG doesn't support the notion of "untrusted" code, and hence doesn't
need the "space suits" provided in C by zope.securty / zope.proxy.

It might even be easiest to ship an app (as opposed to developing it)
with the generated python code on disk, and configure it not to
regenerate at all:  at that point, lxml would be a "build-time" dependency.
