z is the value of the function (Sin[x] Sin[y] in this case) for any given x and y.

=============
Mathematica v7.0 has this sample for ContourPlot[]

ListContourPlot[
 Table[Sin[x] Sin[y], {x, -3, 3, 0.1}, {y, -3, 3, 0.1}],
 ContourLabels ->
  Function[{x, y, z}, Text[Framed[z], {x, y}, Background -> White]]]

Where does the z come from?
Can I say that the x and y come from the iteration by Table[]?
Is z an implicit variable?

Thanks
