Usually the +top level object is a dictionary. + +Values can be strings, integers, floats, booleans, tuples, lists, dictionaries +(but only with string keys), :class:`Data` or :class:`datetime.datetime` +objects. String values (including dictionary keys) may be unicode strings -- +they will be written out as UTF-8. + +The ``<data>`` plist type is supported through the :class:`Data` class.
