 Yes, but people will still invent their own semantics for identifying content if you give them the means. I figured that was what ExternalIdentifiers were for. 

 While we're on the topic of identifiers, can anyone provide a distinction between "name" and "id" in a registry object? Is one composed of the other? Please give examples. I understand that id is implied because the server generates it if the client does not provide it. Does the server also generate a name? Can a name be null in the underlying information model?
