.xar Extension NOT Used Properly

The new way to import/export wiki pages is very useful. However, I think that using the .xar extension for the zip(!) archive is highly confusing. This because there is already a XAR(eXtensible ARchiver) archiving utility which uses the .xar extension for quite a while. And while now XAR is standalone, it will be quite probable used by the MacOSX package system in the future. Then download your archive will yield an error like this (safari automatically expands archives): "Error opening xar archive: xwiki-1.0-beta-1.xar" Links: http://www.opendarwin.org/projects/xar/ http://www.nabble.com/xar-in-Mac-OS-X-t2081148.html
