I hope this isn't official W3C policy because it is very poorly thought out. We at Microsoft are already having problems with the fact that RECs like W3C XML Schema add backwards incompatible changes in errata does breaking our customer's previously working schemata when they get a patch or upgrade for no fault of their own or ours. For the W3C to actually have a policy where versions of their standards never change their namespace URI would have many negative effects across the software industry where XML is used. Either applications that worked perfectly in the past would continually break as changes to the RECs were made or the W3C would have to ensure that every change they made was backwards copmpatible which is an difficult burden and one it has shown to be incapable of doing. Thus I hope and pray this is your opinion and has no bearing on any stated W3C policy on namespace URI for versioning. ===== THINGS TO DO IF I BECOME AN EVIL OVERLORD #79 If my doomsday device happens to come with a reverse switch, as soon as it has been employed it will be melted down and made into limited-edition commemorative coins. __________________________________________________ Do You Yahoo!?
