OK, this isn't necessarily a show-stopper, but I just wanted to be sure that the IESG is aware of the situation. >>> An Ad-ID Identifier consists of a unique eleven character string >>> or a unique twelve character string (video codes only). >> >> What's a "character"?

As I said, I'm not a URN expert, but it seems to me that avoiding any ambiguity by *specifying* UTF-8 would be better. RFC5234 leaves it open: "In certain contexts, a specific mapping (encoding) of values into a character set (such as ASCII) will be specified." RFC2141 section 2.2 also leaves it open by allowing for translation from non-URN characters. >> The informative reference [Ad-ID-INTRO] doesn't seem to know whether it's a >> technical appendix or a reference, and the URL that it cites is unhelpful. >> The material at http://www.ad-id.org/how-it-works/ad-id-structure seems to >> be what is needed but partly duplicates what is in the draft.

If the reader is from the SMPTE world, it may not help, but for readers from the IETF world I think it will do so.
