Hello Barry,

Sorry for the delay in answering your mail.

It's a myth. First and foremost, RFC 3987 clearly describes IRIs as 
protocol elements (it's in the first line of the abstract, so you don't 
have to search for long).

Second, your earlier mail (around July 22nd) said "I believe WF should 
only use URIs.  I believe that IRIs are a presentation layer thing.". 
Surely we should be able to do better than just "believe".

So people on this list are not humans?

What if we had one layer less? Layers are a very convenient thing if 
they add functionality, but not if they add confusion. If we would redo 
email, for example, we would do away with all the base64 and 
quoted-printable stuff, wouldn't we?
