New Revision: 954061

URL: http://svn.apache.org/viewvc?rev=954061&view=rev
Log:
Code gen works for state pattern with xsl. w00t. But for some reason beautify.js is broken.
boo. Next steps are to do some automated unit testing, then to hook up the other backends,
then to replace the rest of the e4x, then finally to try it in the browser.
