4.1.1.  Autocompletion and On-the-fly Validation

OrangevoltXUL supports XUL editing by providing registering the XML schema for XUL in Eclipse Webtools.

Using this schema the Eclipse WTP XML editor is able to do autocompletion and on-the-fly validation while editing.

Please note that this feature is not working that much perfect because of some weaknesses in the current Webtools validation engine. Future versions of Eclipse WTP will solve this problem.
