My feeling is that if pins are numbered the same then they are  
electrically connected in the part.


an example is the 4 mounting pins on a SMA to PCB jack  the 4 outer  
pins are electrically equal,  you can attach to any of them they are  
the same net

PCB wanted all 4 pins connected...  but electrically only one needs  
connection.


Some discussion could be put into this.

do we want sub pins for the net of pins
so on a SMA example

the center conductor would be pin 1
the 4 mounting pins would be pins 2.1, 2.2, 2.3, 2.4

so if the net specified connect to pin 2   it would make a electrical  
connection to any of the pins and be done

if you specified that it was pin 2.1 it would connect to that sub pin.

if you specified 2.*  it would require connection on all sub pins.

this would provide for the most options in how to handle internally  
connected pins with the same numbering.


thoughts gang?
