		'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.

		Lists:
		['tag', 'xml', ['element', 'a', 'b'], ['tagline', 'xml2'],
