2008 Aug 15, 4:02VS debugs XSLT. Didn't know that. Neat. "You can use the Visual Studio debugger to debug XSLT. The debugger supports setting breakpoints, viewing XSLT execution state, and so on. The debugger can be
used to debug a style sheet, or to debug an XSLT transformation invoked from another application. XSLT debugging is available in the Visual Studio Team System and the Professional Edition."
Unfortunately I couldn't figure out how to pass in parameter values... I just ended up setting the default value for my param elements. Otherwise, cool.
