Dan Connolly: >> This may have some uses in a programming language such as Java[Java], but it has a serious flaw in that when one module changes (without the knowledge of the designers of the other module), it can unwittingly redefine a local identifier used by the second module, completely changing the meaning of a previously written document. Clearly, in the Web world in which modules evolve but documents must have clearly defined meanings, this is unacceptable. >> Hi Dan, In programming/OO terms I think you're talking along the lines of the Liskov substitution principle, but I'm not sure. Can you give a quick example? regards, Bill .. InterX bdehora at interx.com +44(0)20-8817-4039 www.interx.comReceived on Thursday, 18 October 2001 10:13:57 EDT
