I'm sorry -- I didn't mean to imply that your processes weren't using well-formed XML, I was just trying to draw the parallel between your acceptance of any *vocabulary* to create a known vocabulary as a result, and JITTs' acceptance of any *syntax* to create a known syntax (XML) as a result. I'm just trying to persuade Patrick not to use a syntax that's similar-enough-to-XML-to-be-confusing as the input to his processes in the examples that he uses.
