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
