Thanks for clarifying that!

(Presumably changing 'ar' to 'gdr' there.)

It seems to me that you might be able to remove the statement about the 
global uniqueness of specific portions of 'gdr' URNs (e.g., the 
<variant> and <kvlist> extensions), unless this is important to you and 
to the ecosystem of registrars.

What we care about most is the GodDaddy Registrar's commitment to 
ensuring the uniqueness of URNs that you create. My impression is that 
you won't be creating hundreds or thousands of URNs. Instead, you're 
going to create a pretty limited number of URNs (maybe a few dozen?) 
which represent "extensions" that are specific to your registry system. 
In that case, guaranteeing uniqueness should be fairly straightforward.

To be clear, the phrase "best effort" in your current text caused 
concern for me, because I think GoDaddy Registrar can do better than 
that for a few dozen extensions. If the phrase "best effort" applies to 
the uniqueness of extension names (not full URNs) across the universe of 
registrars, then that is perhaps nice to have for GodDaddy and the 
registrar industry, but from a URN perspective that doesn't really 
matter to us. :-)

Does this make sense? Sorry to have replied in such a wordy fashion.

Peter
