How do you get consistent "behaviour" from a string? Identifiers don't 
have behaviours. They are just lookup keys. If the thing that is looked 
up is deleted then you get the equivalent of a 404 no matter what the 
scheme. Arguably, this could be correct behaviour regardless of the scheme.

Could you give an example of code that would be written differently 
based on whether the scheme is "urn" or "http" and would have better 
behaviour than if the scheme is just always "http"?
