    <!--
        Note that checkstyle is used to validate contributed code and generally used to fail builds if
        the checks fail.  So as much as I'd like to have, for example, the TodoCommentCheck enabled it
        is just not practical given how we use the plugin.

        The commented-out checks are ones I would ultimately like to (re)enable.
