"Hello World" is proof that the compiler compiles and you can get output to the console, it's not of itself an objective. I'd say the problem is getting stuck on "simple" as in "tossing most of the context". XSLT _always has_ all of XML. XSLT is _expressed_ in XML, XSLT is a programming language expressed in its data structure. That's a design decision, and it was certainly a conscious decision. (One shudders to imagine how such a thing could occur by accident!) As a decision it makes a lot of people unhappy and there is no help for that. It's even arguably clever in the pejorative sense of making things harder to debug. It does inescapably mean you you can't get away from XML when using XSLT. You always have all of XML. You don't have to _use_ all of XML, but you can't toss the context; XSLT is never in a "simpler than XML" context. Design principles always serve a purpose. The purpose is never legitimately "make the solution simpler than the problem" because the solution cannot, by definition, be simpler than the problem. So any time anybody picks up XSLT, they've already decided they've got a problem that isn't simpler than XML. We can hope they're not wrong but that's one of the things using XSLT means.

That's why JSON exists; people who wanted something that was a container for strings and *didn't* make them deal with the full generality of the XML context badly enough to create it. That's not a desire that automatically makes them wrong. -- Graydon, who admits serious trepidation if they want to start expressing user documentation in JSON
