Close working group. In the first case where there is transport level authentication, that is used. For non-authenticated transports, signing the server object and public key description. DoS attacks were raised as an issue and the group agreed that the draft should discuss the problem that adding a level of indirection for resolution raises for attacks on protocols which rely on the resolution. Nico Popp then discussed the extensibility model.
Properties are the main building blocks.
Extensibility through new properties and loosely typed objects. You cannot create new objects from scratch, just properties. There are two property creation mechanisms. This does mean that real collisions of property names are possible, but the the type scope limits the effect of this collision. There are some terminology changes in schema discovery as a result of the different approach to property creation mechanisms.
