Normally I would just put this in my ballot, but since a change was made 
due to a Last Call comment that was discussed here (a discussion I 
missed at the time) I want to comment on this here to make sure there is 
consensus for either the change you made, or for what I will propose:

On 12/19/14 6:06 PM, Nico Williams wrote:

This seems like an exceedingly bad idea to me, for a number of reasons:

1. The use of IRIs as protocol elements is recipe for disaster. I think 
we came to the conclusion long ago that if you are using something as a 
protocol element, it had better be a URI, and you had better 
percent-encode anything that was non-US-ASCII.

2. Normalization is discussed quite reasonably in 3986; 3987 is unlikely 
to add anything useful.

3. The 3987 is currently in a state of limbo. We're waiting to see what 
W3C ends up recommending for HTML5, and the IETF is likely to end up 
referencing that in the long run and not 3987.

Unless folks want to express a strong reason for this particular 
document to reference 3987, I really think you should remove any 
reference to it.
