Whatpm::NanoDOM - A Non-Conforming Implementation of DOM Subset

=head1 DESCRIPTION

The C<Whatpm::NanoDOM> module contains a non-conforming implementation
of a subset of DOM.  It is the intention that this module is
used only for the purpose of testing the C<Whatpm::HTML> module.

See source code if you would like to know what it does.
