   Precisely, that's why I do not want mobyStatus tag  - that is a magic
tag. If I use a normal moby object, I do not need to change anything in
the client tooling as long as my client do not want to call a service
asynchonosly. In that moment, the client obviously becomes more
complicated. But if we use for status normal objects, the complication is
smaller.

   This is a very valid point (you see that I sometimes even agree with
Tom?). I was myself trying to find how axis2 can help us with the
asynchonicity without changing bimoby api (or changing it not much), and
so far I failed to get it. Probably similar it is with other
technologies. We do not have time to study in details such big
products/specs as WSRF is, unless we have to. But we are usually open if
somebody tells us: this and this you can use and it will solve your
problem better. So far, we do not have such person for WSRF...

   Cheers,
