Hey Jacob,
I'd work on that with you.  Job, Morrow and I also started a draft for
Large WKCs, but we have not submitted anything - nor made any recent
progress.

IIRC, the direction we were intending to use 0 (zero) as the ASN, then
define local data part 1 as WKC itself, and local data part 2 to be a
value associated.

I've attached that I have written so far.  Job and Morrow may or may not
endorse this approach at this point.
