[xwiki-users] xpage=xml with versions?

Hello Wikiers, There is, within XWiki 1.5.4, a possibility to export as XML the content of a page, with attachments and everything: curl -O 'http://user:[email protected]/xwiki/bin/view/Main/WebHome?xpage=xml' how can I do the same with all the existing version and authors? Adding &backup=true&history=true did not help. thanks in advance paul
