Various utilities to patch standard Plone content types
PatchPloneContent is a collection of utilities, used to add or alter how standard Plone content types work using the monkeypatch technique.
Variables of interest in this module are content_types, a tuple collection of the class definitions of standard content types.
The functions of interest are content_classes_add_fields, which accepts a sequence of content classes as the first argument, and a sequence of fields to add as the second argument. As well as add_validator, which inserts validators into fields.
Should work with Plone 3 and 4, maybe 2 as well.
Note that archetypes.schemaextender is a perhaps bit more difficult product to use but more powerful.
