My thinking is that the right tooling for this job is not pure XSLT, but XSLT+XProc. XSLT is designed as an XML transformation language, and I think it's a mistake to try and get it to cook your breakfast for you. XProc, by contrast, is designed as a language for integrating different technologies and making them work together: XForms, XQuery, XSLT, and if you need them, components written in low-level Java or C# code. I think you do need a level of the system that can sequence work in a defined order (because when you're talking to users, the order in which you do things matters), and that means a purely functional language isn't ideal for everything James talked about building a Java framework for doing this integration task, and for the high end applications that may continue to be necessary, but I'm optimistic that for the other 95%, XProc will meet the requirement.
