Hi Otmar,

I have expressed the same worries about it, and Patrick and Olaf
considder this a layer nine issue rather than something they're trying
to solve.
Not only for open numbering plans, but also for block allocations, ENUM
v2 offers no solution for the authority over the delegation problem.
I considder this the real issue, and even though ENUM v2 will solve
direct querying for specific records, the increase in delegation points
will not have any value for non fixed length numbers, and might even
confuse people even more.
But they do have a valid point when they say that any (new) type of
operator might claim their own tree to control their ENUM space, and we
need a solution for that. I think that differentiating should take place
as close to the root as possible to make sure that implementation is the
same around the world, and applications know where to query.
