[xwiki-users] Why do version numbers increment when nothing has changed in a save?

Hi, When I click edit on a XWiki page and "Save and View" or "Save and Continue", without making any changes, a new version number is created. This is contrary to existing conventions in SVN, which will intelligently check whether there are any modifications that would warrant a new version number. Is this a fundamental different view of the XWiki development team or is it a technical difficulty or simply something that has not been implemented yet? Also, why is the first version of a document 1.1 and not 1.0? Thanks, Andreas
