I've sort of mentioned this a couple of times, so if you are tired of
hearing it you have my permission to thump me over the head...

Even though the URN isn't supposed to be parsable by humans, I
suspect that it will be *copied* by human fingers every now and then.

Might it be useful to tack on a 4th field which is some sort of
Hamming-like code to detect and perhaps even correct single character
typos, transpositions, CaSe FlIpS, or character omissions?

This might also help the URN resolver to weed out obviously invalid
ones before engaging in an expensive search.
