ObservableArray and Namespace

[bathos]

The part of the attribute getter algorithm responsible for returning the backing OAEO is only reachable for attributes whose target is an interface. However it doesn’t seem like anything forbids the regular attributes of namespaces from having ObservableArray as their type.

It seems like either:

1. the constraints for where ObservableArray is usable should say “...of interfaces” or
2. 1.1.2.4 of create an attribute getter should be lifted up to be between 1.1.2 and 1.1.3.

(Though I’m not sure which is what was intended.)

Edit: seems like it probably should be the first, since the backing array is keyed by the target object. This would seem to imply a namespace member that exhibits branding, which seems undesirable.
