Wouldn't it be easier, more consistent, cleaner, and cherry-free to keep 
what we've already proposed in draft-09, that is, to include the 
Macrolanguage field in the registry as informative information (and then 
note in either 4646bis or 4647bis about possible courses of action in 
cases of match failure)?
