 It occurred to me, while I was considering the issues relating to stylesheet library modularity with respect to dynamic scoping, that global parameters and variables already present a problem (if I'm not mistaken). I'm not sure what problems you are identifying. In my opinion, they ought to have been scoped to the file in which they're specified. You can choose to do this by namespace-qualifying your variable names, without changing the design of the language. I'm concerned that (assuming I'm not mistaken), if these issues aren't addressed, it may be very difficult for stylesheet libraries of any significant complexity to be developed and used, successfully. I think you may be mistaken. I've found the ability to declare a default value for a variable in a given module and then import that module overriding the initial value for that variable to be *very* powerful. I've used namespace-qualified variable names in an imported stylesheet to ensure an importing stylesheet cannot "accidentally" declare a variable that would unintentionally override the variable used in the imported stylesheet. Furthermore, this would also provide more static optimization opportunities to XSLT processors supporting some sort of evaluate() function which supports variable references. I don't think losing the implementation benefits would be worth it. ........................ Ken
