@property<EOL><INDENT>def ordered_tags(self):<DEDENT>
return natsort(self.tags.values(), key=operator.attrgetter('<STR_LIT>'))<EOL>
The values in :attr:`tags` ordered by tag name (a list of :class:`Revision` objects).

The list is ordered by performing a `natural order sort
<https://pypi.python.org/pypi/naturalsort>`_ of tag names in ascending
order (i.e. the first value is the "oldest" tag and the last value is
the "newest" tag).
