There are 2 main problems with XSLT. The first one is that manipulating strings is a pain. Splitting strings, concatenating them is verbose like hell and difficult to read. The second one is that it quickly becomes a mess when you use the "priority" attribute to overload functions. I compare XSLT to regular expressions, with great flexibility but impossible to maintain due to poor readability. To my knowledge, it's impossible to trace.
