We don't really have places where "command" or "function" would be appropriate AFAIR. As for "option", what's the distinction between that and "parameter"? And why wouldn't I use "<option>" instead? Even if we did have uses for the other class values, I'm skeptical that we'd ever use them consistently enough that there'd be value in rendering them differently. regards, tom lane
