Assign a "flag" to this document. Flags represent key-value type data which can be used to store flexible or arbitrary data required by either the core software, game systems, or user-created modules.
Each flag should be set using a scope which provides a namespace for the flag to help prevent collisions.
Flags set by the core software use the "core" scope. Flags set by game systems or modules should use the canonical name attribute for the module Flags set by an individual world should "world" as the scope.
Flag values can assume almost any data type. Setting a flag value to null will delete that flag.
