Yes, I know the common definition. But, like I said, I was told by someone who claimed to know better, and, thinking about it, I think he's right. Since some people, like Peter, hypothesize that it's an extreme example of evaporation and not sublimation, :-), I'm going to go poke my nephew the chemistry student and see if I can get a pointer to an authoritative explanation. How's that?
