Edited my previous statements on section 5. Thinking about it some more, I do wish we had every reasonable feature that section 5 and the SOAP spec allows (multidim is at the top). However, real-world engineering has limited that goal in V1. V1.1 is a little better. And V2 will even be better than that. The SOAP Toolkit has been a good model for that (especially since they've been able to ship so often.)

As an aside, I use to feel that subsets were a bad idea. At this point, I don't think interop can happen without them. I hope that the WS-I basic profile gives us a reasonable one involving WSDL, SOAP, XSD, etc...
