I don't understand this critique. Your paper criticized the DSSSL Transformation Language, which AFAIK was never really implemented by anyone. XSLT derived almost entirely from the DSSSL Style Language, as augmented by the element, attribute, etc. psuedo-flow-objects that James Clark implemented in Jade. >However, why couldn't XSL have taken advantage of basic principles of >programming language design?

True, the templates aren't *lexically* scoped with modes, but most reasonable developers put all the templates in a single mode next to each other. (Although some will put all of the templates for a node type next to each other, which is also reasonable.) In some ways, scoping via modes is a bit more flexible for program readability than lexical scoping. -Chris -- Christopher R. Maden, Principal Consultant, HMM Consulting Int'l, Inc.
