@pvillard31 yeah at this point, the properties are given to use in a Map
and not in any guaranteed order. So the updates are applied in some arbitrary
order. If you have conflicting "rules" then there's no real way to determine
what order they will be evaluated in. So if the first rule ( / =>
/accounts[1]/* ) is evaluated first then /name will evaluate to `null`.
Otherwise, the /name will be updated and then the other rule will overwrite
it...
