This is where Space security definitions are created. Before an security definition can be applied to a space/space element, it needs to be defined.
Attribute definitions consist of the name of the security definition, a message used if the definition is applied and then violated, a type (always Space in this particular place), and the actual rule (in KSL).
Determines what information is available to the definition rule and message, as well as what security policies the security definition can be applied to. In this case, it can only be space.
The human readable reference that will be displayed in security policy dropdowns.
The message that is returned to the user if permission is denied.
