Dexterity Versioning Does Not Appear to Work

you're missing a couple of things that must be done in the ZMI and/or Types configlet (I don't remember right now).

an example from one of our projects using GenericSetup:

diff_tool.xml

<?xml version="1.0" encoding="UTF-8"?>
<object>
  <difftypes purge="false">
    <type portal_type="collective.nitf.content">
      <field name="any" difftype="Compound Diff for Dexterity types"/>
    </type>
  </difftypes>
</object>

repositorytool.xml

<?xml version="1.0"?>
<repositorytool>
  <policymap purge="false">
    <type name="collective.nitf.content">
      <policy name="at_edit_autoversion" />
      <policy name="version_on_revert" />
    </type>
  </policymap>
</repositorytool>

this needs to be documented.
