This is unfortunate, but really a problem for the lxml community and
not us. So the lxml community cannot keep up with providing binary
Windows eggs.  This cannot force us to stick with old and buggy
versions of the software.

2.2.6 was the latest stable version available at the time of the
release. 2.2.7 had known problems with newer libxml2 versions, but I
see there's a 2.2.8 out now, which we should update to.

I'm not sure about the actual dependency situation. I think it's more
or less a convenience pin, as lxml is used very often in Zope related
projects. We provide a known good version for it in the Zope Toolkit
KGS for the same reason.
