Re: Question: UseSTD3ASCIIRules on RHS of IMA

   IDNA suggests that applications that simply passed things on before
   should not set the flag, and applications that enforces hostname
   restrictions today should set the flag.  Application have made a
   decision, conscious or not.  I'm not sure I see any need to enforce
   anything with regard to this more than already is, and in particular
   not how IMAA would be the right place for it.

Ok, maybe you're right.  However an informational note would not go
amiss, even if it's only on the lines of the note in IDNA that
basically just says 'this point is contentious'.

Further minor wrinkle: if the application chooses not to enforce
hostname rules (ie not to set UseSTD3ASCIIRules), it still needs to
enforce those retrictions on domain names that occur as a result of
the 822/2822 syntax (ie a label can't contain specials).  Does IMAA
need to say anything about the application of the 822/2822 rules (in
the same way that IDNA talks about the application of the STD3 rules)?
