I think this shows more than ever that we need to accept that references can and should have less detail than definitions, and start distinguishing the two.

- Community names such as =neustar*les don't work anymore, because the instance *les can't follow the singleton =neustar. Do you have any idea on how to solve this?

Markus and I talked about this for nearly an hour. The bottom line is that to be consistent with the full XDI graph model, *names and !numbers need to behave consistently as instances, which means they only follow a class (in square brackets). So it means that community names need to specify the class before the instance, e.g., =neustar[+employee]*les. Or they can use a cross-reference such as =neustar=(les). Or, for a pure name registry, it would be an instance of the mutable ID class, e.g., =neustar[*]*les. (Ugly but semantically consistent.)
