If so, what about the "coercibility" property? The standard defines four distinct coercibility properties. So in above my example, actually you are going to define 80 new types? (also a collation could be either "PAD SPACE" or "NO PAD". So you might have 160 new types). -- Tatsuo Ishii ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
