@milseman, @doug.gregor, could you please help with the open questions on this review?

Specifically:

- Is `ns_error_domain` ever needed for something other than an enum?
- Why is this designed in the way it is (requiring an identifier for the domain, not allowing literals and then only using the name of the identifier from Swift)?
- Is it ok to make this attribute inheritable?
