HTML::Microformats::Format::hReview::rating - helper for hReviews; handles the rating property
=head1 DESCRIPTION
Technically, this inherits from HTML::Microformats::Format, so can be used in the
same way as any of the other microformat module, though I don't know why you'd
want to.
It does not implement the include pattern, instead relying on the hReview implementation
to do so.
=head1 BUGS
Please report any bugs to L<http://rt.cpan.org/>.
