Looking at the port itself, you will see:

                       U
                   3       1 
                
                  5          4

                       2

Pin 1: Composite Luminance (not connected)
Pin 2: Ground
Pin 3: Audio Out
Pin 4: Compoite video
Pin 5: Composite Chroma (nc)

One goofy thing I found was that with a mono monitor, the screen looks
messed up, like every other pixel was skipped.  I found that by
connecting the composite video to either Pin 1 or 5 (I can't remember
which), it cleared it up.  I don't know if that happens on the XL/XE,
but it did on my 800.
