Hi, Pete. I don't recall who exactly came up with new interface suggestion, maybe it was me based on IA2 architecture in Gecko.
Assuming you meant new relation rather than object attribute I believe relations approach work as generic approach. Any getter property that returns an object mapped well to relations mechanism, for example, IATable2::caption property can be exposed by relations. The question is when we want to introduce new method rather than reuse existing generic-propose method. Thank you. Alex.
