When using this widget, the vocabulary/source has to provide the IQuerySource

+interface from z3c.formwidget.query and have a search() method. The easiest
+way to do this is generate one with one of:
+* plone.formwidget.contenttree.PathSourceBinder(navigation_tree_query=None, **kw)
+* plone.formwidget.contenttree.ObjPathSourceBinder(navigation_tree_query=None, **kw)
+* plone.formwidget.contenttree.UUIDSourceBinder(navigation_tree_query=None, **kw)
+Where ``navigation_tree_query`` is some restrictions that should be applied to
+any Catalog query. The rest of the arguments are used to form a filter (see
+``PathSourceBinder`` and ``ObjPathSourceBinder`` store the selected object's
+path in the field value. This means that the link will be broken if the object
+is moved. ``UUIDSourceBinder`` stores UUID references, so will handle pages
+being moved.
+If you do not want to filter the content tree whatsoever, there are some
+pre-baked instances too:
+* plone.formwidget.contenttree.path_src_binder
+* plone.formwidget.contenttree.obj_path_src_binder
+* plone.formwidget.contenttree.uuid_src_binder
