David:
I think one needs to carefully parse the xyplot help, where it says:
"To use more than one legend, or to have arbitrary legends not
constrained by the structure imposed by key, use the legend argument.
"
So I presume that this is to be interpreted as: "ONLY the legend
argument will be used when both key(including auto.key) and legend
arguments are given." However, this is not clear to me either. The
Help appears to leave the behavior when one tries to use both
unspecified.
