CONFIG PARAMETER: attr_access <attr> [!]<privilege> [[!]<privilege>]...
The attr_access configuration parameter changes the access rights to the named attribute. Named attributes are within the set defined by the server. Server defined attributes are those set by common @-commands such as @fail. The controllable list can be seen by using @list attributes. User defined attributes set by the & command such as &dat-player-stats are controlled by the @attribute command. User defined attributes access cannot be adjusted through the attr_access parameter.
The available permissions list is detailed under ATTRIBUTE PERMISSIONS. Preceding a permission by ! removes that permission from the required set.
