Expand description
Read-write command metadata variable.
The boxed var is an ArcVar<T>
for app scope, or ArcCowVar<T, ArcVar<T>>
for scoped commands.
If you get this variable from an app scoped command it sets
the value for all scopes. If you get this variable using a scoped command,
it is a clone-on-write variable that overrides only the value for the scope.
