Thanks!

I'm sure that we can learn much from each other, and the specs we 
produce will benefit as a result.

To start off, I'd like point out one area where there may be some 
technical issues that you might not be aware of -- and I encourage you 
to do the same with specs I am working on.

So as to not affect the call for adoption, I've changed the subject line.

The area I've chosen to focus on first is host names -- something that 
is particularly thorny.  The RFCs you reference don't quite capture all 
of the necessary behavior.  I encourage you to explore the following 
URIs.  In particular, I recommend exploring these with the Chrome browser:

file://2130706433/foo
file://[2001::1]/foo
file://０Ｘｃ０．０２５０．０１/foo

Note that the last one is using Unicode wide characters.  An alternate 
representation would be as follows:

file://\uFF10\uFF38\uFF43\uFF10\uFF0E\uFF10\uFF12\uFF15\uFF10\uFF0E\uFF10\uFF11/foo

You may find the following online tool to be handy for exploring cases 
such as these:
