Review comment:
Thats a good point about the key and in general this will become a problem
for all artifacts since none of them have unique keys associated with them
unless an intermediary resolves the artifact immediately and possibly "renames"
the contents to make it unique.
If we ever want to support multiple layers of expansion for XLang we'll want
to proxy any artifact resolution/retrieval calls through the layers and not
require each layer to have a *copy* of the artifact.
