Validating help content XML and HTML files: The Eclipse help system expects well-formed XML
			
If validation fails it is because either:
			
* the userguide source code is poorly formed, or
* the WikiText MediaWiki parser has a bug
			
Problems with userguide source are usually caused by improper use of HTML markup in the MediaWiki source,
or inadvertently starting a line with a space character (in MediaWiki this starts a preformatted block)
