I've run into a few different levels of interop problems: 1) Developers who can't even figure out how the URI side of things works and can't find vocabulary to talk with each other about it. (This level of frustration seems mostly ignored here since we've all talked it to death.) Many of these people say screw it and simply use the QName as an identifier, ignoring the URIs completely. This produces much simpler code that works - up to a point. (Yes, I've since this in the wild, and repeatedly.) 2) Developers who build applications for local systems where they have complete control over how a URI gets processed (heck, throw an XPointer on the end of a URN!) who are then unpleasantly surprised if their documents ever have to be processed in a different environment. 3) Developers who put something at the end of that URI, typically a schema, thinking everyone else does it, only to find that other people think their documents are weird, but that incoming documents are also bizarre. Sure, experts on namespace can sort this all out. Does that mean the spec made sense in the first place? How many experts does it take to get namespaces right? The only genuinely surprising thing to me about namespaces is that we've put up with this for so long. -- Simon St.Laurent Ring around the content, a pocket full of brackets Errors, errors, all fall down! http://simonstl.com
