        There are three types of lists that are recognized at this
        time.  They are as follows:

        'tag' - Tag opens a set of data that is eventually closed
        with a similar tag.
        List: ['tag', 'xml']
        XML: <xml></xml>

        'tagline' - Taglines are similar to tags, except they open
        and close themselves.
        List: ['tagline', 'xml']
        XML: <xml/>

        'element' - Elements are pieces of information stored in an
        opening tag or tagline.
        List: ['element', 'color', 'blue']
        XML: color="blue"

        'data' - Data is plain text directly inserted into the XML
        document.
        List: ['data', 'hello']
        XML: hello

        Bring them all together for something like this.
