Len, You are confusing the specification of the data with the execution of the specification. It's like saying there'd be some difficulty in representing a programming language using XML syntax--there's not. Using a style language is useful for the same reason it is in SGML: I want to apply different styles to the same basic data objects. Asking why it's useful here is like asking why you need styles if you have a font tag and I know we both know the answer to that one. The fact that the presented result happens, in some presentation styles, to be interactive is completely irrelevant to the issue of representing the data using XML. A better question might be: does XLL (or HyTime event schedules or some combination thereof) provide anything useful in representing the relationships among the nodes, which is all an event model does (define relationships or behavior associated with relationships). XML only operates at the document representation syntax level, so it can have nothing to say about the semantics of the data represented. On the other hand, XLL and HyTime (and DSSSL and XSL) operate at the semantic level and therefore may have lots to say about the semantics of the data represented.
