The draft currently says it is undefined.  This 
is not the same as prohibited.  A future draft 
can extend this one by specifying how it is used. 
I think it's better to keep this draft as simple 
as possible, so if we don't expect this to be 
used, let's not add text about it.  If it does 
seem useful in the future, it can be added with 
minimal fuss.
