Singe HTML documentation (of Drools Expert) is broken from chapter 5 's first SVG image (in section railroad diagrams) onwards on firefox 5 beta 1

"Having a look at it with the html-tidy plugin from firefox there are several </span> tags which are too many and more likely the object tags are not closed correctly (you use xhtml so you need to close then with </object> the empty tag structure <object/> is invalid in xhtml)."
