Maybe I've missed some discussion, but I don't quite understand the
second component proposed for the URNs.  In -02, it is shown as
"urn-xxx" (with the initial scheme "urn" omitted, which you have since
fixed).  In your message that I am replying to, it is shown as "urn-7",
which seems to be part of a series "urn-N" for defining URNs for local
use.

But given that 3GPP is interested in this, don't they already have a URN
namespace selected?
