Thanks for processing my mumbling above. I was not sure I'm on the right 
track, but if you say it sounds sensible I guess we are done with it and 
don't need to get _more_ WG input on these nits.

>>> 3.1.2. Private Use Range

Otherwise we would need sub-range for experiments, and I think it is not necessary.

Really up to the WG, I'm indecisive on this myself.
