I took the phrase "reasoning about the relationships" to be of wider significance -- similar language has been used in your and Greg's discourse on the (alleged) need to know what the endpoints are up to, and thence to the idea of an ACID-only protocol, which I think is a rather stunted beast. The fact that the declarative use of the transaction context on receipt by a bean is a private matter is one example of the ability to be largely ignorant of what transactions means to the interlocutor, but still be able to make use of them. On the narrow point, it seems that any way of marking an endpoint as being capable of receiving a context is better than none. In that respect I think that fixing on something that actually works is better than trying to second-guess the next three twists and turns on the secondary roads running through WS-Land. Is there a way of doing this which will work with current WSDL and not just 2.0? Alastair Alastair J.

There's no equivalent of CosTransactions::TransactionalObject and because IIOP is not mandated, there's no way of delving within the object's IOR at the client side.
