Namespaces

Fallout 4 added Namespaces to the language which can be used to better reference other Scripts. A namespaced identifier uses multiple identifiers separated by columns (:):

ScriptName Quests:MyQuest:Script1

Namespaced identifiers can be used whenever referencing a script:

ScriptName Quests:MyQuest extends Quest

; Quests:OtherQuest is another Script that extends "Quest"
Quests:OtherQuest Property TheOtherQuest Auto Const
