I can.

  "container.aq_base" is "container" without any acquisition context.
  "getattr(container.aq_base,attr)" is "attr" in the context
  of "container.aq_base". Further acquisition context is missing.

  "getattr(container,attr)" is "attr" in the context of "container".
  It has full acquisition context.

If it is not clear, read the "Acquisition" section in

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

and draw some acquisition trees.
