> do you have an example? Not one that can be published without a considerable amount of work, unfortunately. But to take one example, a client was churning out multiple stylesheets to do different reports on the same data. They were all 90% the same. We found a way of parameterizing it by reading the sort criteria and grouping criteria in the form of XPath expressions held in a report definition document, and evaluating them dynamically within a highly recursive framework stylesheet, and all of a sudden we could produce any report the users wanted just by changing a couple of lines in the definition file.
