I'm in a bit of a weird spot. Due to events too ridiculous to list here, I'm working with a system that uses an unknown XSL engine. I'm fairly certain it's MSXML. The problem is that I'm not entirely sure which version (this is important). The original devs aren't available, and I have very limited access to the back end. What I do have the ability to do is author content (that gets fed through the XSLT sheets) and to edit the XSLT itself. Given these two abilities, is there any way I can make the parser report its version? Anything like PHP's phpversion()? Maybe even a standard way to report the XSL engine vender and version?
I'd be very willing to write a feature check sheet, if I could just find a list of XSL engines, and features unique to each.
