  HTML::HTML5::DOM class methods
    While most of the interesting stuff is in HTML::HTML5::DOM::HTMLElement
    and other classes like that, the HTML::HTML5::DOM package itself provides
    a handful of methods of its own.

    *   `XHTML_NS`

        Constant. The XHTML namespace URI as a string.

    *   `getDOMImplementation`

        Gets a singleton object blessed into the HTML::HTML5::DOM class.

    *   `hasFeature`

        Given a feature and version, returns true if the feature is supported.

          my $impl = HTML::HTML5::DOM->getDOMImplementation;
