You can consult a Javadoc-style framed Xul tag reference sporting cherry-picked real-world examples from around the globe at http://luxor-xul.sourceforge.net/xulref/.

If you prefer an all-in-one Xul tag reference instead of a heap of loose ends for printing on a papyrus roll, swing over to http://luxor-xul.sourceforge.net/luxorref.html.

Take away. I will bundle the framed Xul tag reference with the upcoming Luxor Beta 5. Check back in a week to get your offline copy.
