I don't understand what 'overlap' you think will exist, but am pretty 
sure I don't agree.

If it is that battle-hardened for this type of use, then there is no 
doubt a single term in the draft that has already gained widespread use.

Which one is it?

And yet that's the distinguishing name of the attrleaf table in the 
drafts and has been for quite a long time.  There haven't been any 
objections to that term until now.

Perhaps you have some usability data that demonstrates pragmatic 
superiority of a particular choice over 'global' for /this/ kind of use 
and can point to the entry in the bis document that already defines it?

Note that the choice echoes the use of 'global dns' that /is/ listed, to 
get at the semantics of the 'reach' for the highest-level underscore name.

Except that that has no obvious semantic merit, whereas 'highest' is 
directly motivated by referring to position in a hierarchy.

Why?
