Does comprehensive documentation on LUXOR exist?

I am trying to use Luxor but can't find documentation on tags.

For example the only info on <componentref> tag is:
----------------
 <componentref>
 References gooey components that are registered with Luxor XulForms so
that you can embed them inside boxes. You can also change their
 style, access key, tooltip and more. Note, that you are not limited to
classic components such as listboxes, labels, etc. you can reference
 hard-wired Java panels as well.
 Note, that gadget is synomym for componentref in case you prefer a
shorter and fancier name.

 Appears In  boxes
 Examples  <componentref id="MANIFEST_TABLE" />
------------------

How to register component with Luxor XulForms?
How to change style, access key, etc?
How to use it?

Does comprehensive documentation exist with details and code examples
for each tag ?

I wanted to use this tag but can't find single example of it's use
anywhere.

Thanx,
Yuri
