The Unicode data table /UnicodeData.txt) doesn't tell us what 10FFFE and 
10FFFF are; the last character listed is 10FFFD (Plane 16 Private Use, 
Last).

On the other hand, Blocks.txt says:

unicode/Blocks.txt:100000..10FFFF; Supplementary Private Use Area-B

So is there a distinction between 10FFFD, 10FFFE and 10FFFF, and does 
this document need to make that distinction?

(I think it's unreasonable to allow any of them in domain names, so they 
should all be DISALLOWED, but i'm not surprised that there's 
inconsistencies here.)

The RFC Editor has strong opinions on where to use titlecase. I always 
get changes when I submit RFCs, so I have left that evaluation on his table.
