This applications rewrites a BWS document to an BWS/HTML
document.
BWSApplet
This applet handles DOM->BSF communication, passes scripts from
the document to their respective scripting engines and provides
methods scripting languages can use to access and manipulate DOM
objects

** Class BWSDocument.java
** 2003-11-24 by Tobias Specht
*******************************************************************************
** This class represents a BWS-XHTML document for parsing and rewriting
** purpose. It provides methods to read an BWS conform XHTML document from
** an URL and rewrite it as an standard JavaScript XHTML document that can
** be interpreted by a standard compliant web browser. It uses dom4j for
** DOM manipulation, so if you want to compile it, make sure you've got the
** dom4j classes in your CLASSPATH.
*******************************************************************************
**
** Changelog
** --------**
** V0.1
@ 2003-11-24
**
*******************************************************************************
*
* - rewriting code must be changed to enable argument passing, cf. bws wiki
*
http://openfacts.berlios.de/index-en.phtml?title=BSFWebScripting
* - allow printing only the final xml document (for redirection)
