Hm, yeah, that's an idea. It's the computer equivalent of Dr Who's all-purpose remedy: Reverse The Polarity.
Incidentally, while doing some mass-replacing-- I'm adding <lang> tags bit by bit as I edit pages-- I realized that
:: cough, cough ::
I really am using <i> for two different things. One's basically presentational ("the letter <i>p</i>") while the other is semantic ("as Goethe famously said, <i>Donnerwetter!</i>"). One goes with <lang> tags, the other doesn't. This tells me I need to attack some of those docs at a lower level. At a minimum, <em> vs. <i>. But for now I compromised by saying <i lang = "iu"> which looks droll but does the job.
