Hi Tom,

What really matters for the IANA early allocation is that the behaviors
associated to the code points are clear and stable. Assuming the WG
agrees on moving to the "binding value" terminology all along the
document, then the technical specification wouldn't change (i.e. it
would clearly be backward compatible [1]) and we could update the phrase
in IANA entry accordingly at final allocation time.

Cheers,

Julien

The I-D does use 'binding value' in one place as what appears to be one of the many different terms for this concept and I think that term much better.
