XEM and Curriki duplicates

Hi, I've noticed that the curriki and xem project duplicate a lot of content from the XE wiki. Just to give an example: - XWiki.Results - Admin.CopyDocument XE is being improved almost daily and as these are copy XEM and Curriki are not improved on their side. Also if they make improvements to these pages XE won't benefit from them either. I think we should not duplicate pages unless they are modified by XEM or Curriki. And even when there are modifications we should discuss how we could refactor the page to have common parts shared. This could be achieved by splitting the page in 2, or by creating templates or by creating new APIs for example. WDYT? Thanks -Vincent
