Exclusions in V6

The new Exclusions option in V6 is quite nice. The following works: Plot[Tan[x], {x, -3 \[Pi], 3 \[Pi]}, Exclusions -> Cos[x] == 0] However, in view of the Exclusions Help page: "Exclusions -> Automatic excludes all subregions where discontinuities are found in functions being plotted. The discontinuities can involve either finite or infinite jumps in function values." I don't understand why the following fails. Plot[Tan[x], {x, -3 \[Pi], 3 \[Pi]}, Exclusions -> Automatic] -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/
