William: Much of what you have said makes sense , the only thing that I want to add is that although there should not be any means of accessing groups of attributes in standard WSDL (as you point out, it doesn't make sense semantically), there is nothing to stop the Grid (which is an application framework) from creating "global getter" and "global setter" operations. These are not quite the same as SDEs since if WSDL supports attributes then it is known in advance the schema of the message that would be sent/retrieved in a global get/set (because you can see the attributes in the interface). This actually removes one of my biggest hangups about my current understanding of SDEs - namely that you suddenly get a bunch of XML and you don't really have any clues about its contents because you have nothing to match them against. Introduce attributes in WSDL and the global get/sets in the Grid framework and things seem to fall comfortably into place. Jim
