Xen includes the latest CVS versions of Acquisition.c and
ExtensionClass.c, as it claims to need these. As they are not included

He wants to directly include references to other Zope objects (stored
elsewhere in the ZODB) from other Zope objects, from the web-interface I
believe, going beyond the current tree-structure.
