XML does not help anything. It is just something that lets you store a tree of config in a flat text file. Nothing more. The meaning of the tree is still a problem. Anyone that thinks XML solves all config parsing problems and makes files underversal and supported clearly has no idea what XML is. That would make Microsoft very happy however. A downgrade quite simply requires a time machine. After all the developer has to write support for converting a future format into a current format when you downgrade. The new version has the ability to upgrade old versions to new, and that is of course tested. It does not have the ability to convert back (and to what version)? At least in debian packages, it is the package being installed that is responsible for any conversions, not the one being removed, so on a downgrade the newer package doesn't do the conversion, and it would be the only one that could know how to do it (although it would probably have very little testing, if it was done at all). -- Len Sorensen -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
