Documentation

I just spent several frustrating hours trying to implement a slide show (not the "Slide Show" in TikiWiki, but rather a small one on a page implemented in JavaScript). I ultimately discovered that the problem was due to the JS plugin converting "", and "&" in my literal strings into HTML entities. I'm not sure why this design decision was made, but it sure ought to be mentioned in the documentation. I put a note there, but a real expert should probably make sure it is correct.
