If we would stipulate node identity say for the XQuery in question or an equivalent XSLT, this would result in a massive vendor lock: The node model used in the XProc implementation, as well as in p:xquery and p:xslt would need to be the same. Any conversion what so ever will al least threaten node identity, so no conversion could take place. The second point is that it would dramatically reduce the number of available tools as basis for step implementation. I could not choose the tool which (I think) is best for users, but I had to choose a tool which is able to preserve node identity. So focusing on node identity would effectivly result in inferior XProc implementation. Achim
