How on earth do i translate display name etc on custom reports?

The report page gives me a hint on whats missing:

/reportcenter/report[@name=""]/description does not exists for language Swedish.

My best guess would be that in my language file, i should put:

<?xml version="1.0" encoding="utf-8" ?>
<languages>
  <language name="Svenska" id="SV">
    <reportcenter>
      <report name="reportname">
        <description>Whatever</description>
      </report>
    </reportcenter>
  </language>
</languages>

But that doesn't help. I also guess a should some how be able to get all other attributed from lang file, like Category (as shownb below), but i cannot figure out how!

[EPiServer.PlugIn.GuiPlugIn(
Area = EPiServer.PlugIn.PlugInArea.ReportMenu,
Url = "~/reporturl",
Category = "custom reports",
DisplayName = "report")]

Any ideas?
