public class PermissionTag extends WikiTagBase
Tells whether the user in the current wiki context possesses a particular
permission. The permission is typically a PagePermission (e.g., "edit", "view",
"delete", "comment", "upload"). It may also be a wiki-wide WikiPermission
("createPages", "createGroups", "editProfile", "editPreferences", "login")
or the administrator permission ("allPermission"). GroupPermissions
(e.g., "viewGroup", "editGroup", "deleteGroup").
Since 2.6, it is possible to list several permissions or use negative permissions, e.g.
<wiki:Permission permission="edit|rename|view"> You have edit, rename, or view permissions! </wiki:Permission>or
<wiki:Permission permission="!upload"> You do not have permission to upload! </wiki:Permission>
