Almost -- it is space-delimited, not comma-delimited:

  "item1 item2 item3"

The clincher is the implementation, in
 $ZOPE_HOME/lib/python/ZPublisher/Converters.py::

  def field2tokens(v):
      if hasattr(v,'read'): v=v.read()
      else: v=str(v)
      return split(v) # this is Python's string.split()
