You are right, of course: there's absolutely nothing to stop me using the html:p element to mean "transfer lots of money to my bank account". Indeed, if you and I had a private agreement to use it that way, we could build a perfectly workable system that way. But XML is often used in a publishing context, rather than a point-to-point messaging context, and explicit private semantic agreements are neither possible nor necessary. A tacet agreement to use the meanings defined by the owner of a namespace is perfectly workable. -- Cheers, John
