I think I found a bug (and 'fixed' it), introduced in 2.0.2: I now cannot use a root element in an xsp-page other than xsp:page. Until 2.0.1 I could use
which was transformed by our logicsheet to
    <request, session etc >
         content of the sun:content
which was then processed by the xsp logicsheet.
I found that the new CocoonMarkupLanguage.java has an extra check on line 258. I 'fixed' the problem by removing the check. The check is probably usefull, but maybe it should only be done in case of the sitemap language?
