I can, I however need to stress that today these questions you ask me
are about an imaginary world in my mind and not about reality. Since I
cannot predict the future I can evaluate on what I know about the past.

yes, but integrity of information is delegated to the client.
Reason: No structure on the served documents means that all associations
and relation between GLUE2 entities have to be computed by the
client(s). The clients have to build their own database themselves.
On the other hand it will happen for XML with the flat structure, so
we're at least consistent on this side :)

My istinctive answer would be no, but I'll smooth it to "hardly".
Reason: We're still having problems within ARC and gLite after years of
operation... even after the integration effort the architectures are
having troubles agreeing on things. But maybe it's just the two of us.
Interestingly, some of the issues are also on several attribute values,
not just the DIT.

But I guess these answers were obvious on my side, especially the second
one is the whole reason why I do care about this.

I'd like to hear other people's opinion on these.

Cheers,
Florido
