The term is in reasonably common usage. Given that, it's notable that Faldage finds, after googling, that "one explicit definition matches."

If out of so many google-hits only one supports this usage of the term, I'd conclude that that one is flat wrong. My logic is what tswum just now expressed in another thread: I don't believe that...in spite of what one misguided web site says.

Although I must also agree with mav that such a difiniton would make a great deal of sense.
