ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.
