[xwiki-devs] What does "import translation file" mean? It doesn't work.

I'm trying to translate the XE Simplified Chinese but have a question. On this page: http://l10n.xwiki.org/xwiki/bin/view/XE/XWikiCoreResources, there is a link "Import/reimport default language file". And after each specific language, there is also an "import" link. What it means? I guess it will pull the resource file from the svn trunk, extract all (variable names, English text) pairs, so that someone can start providing more translations. I'm I right? But the import functionality seems broken. When I click "confirm import" it says, "Error number 4001 in 4: Error while parsing velocity page XE.XWikiCoreResources Wrapped Exception: Failed to evaluate content with id XWiki Core Resources" -- -- Currahee! We stand alone together!
