Please note that the <publisher> and <release-notes> elements in a description.xml are currently not used by the Extension Manager. However, when uploading the extension to the extensions repository (http://extensions.services.openoffice.org) then these elements are used for generating update information. When the Extension Manager looks for updates then it displays this information (OOo 2.4).
