An example labeling contours.

[Ma]

Dear All
This is very nice example, but in most countries the labeling on the
contour lines has a rule:

This is CORRECT:
  -------------  900 ---------

---------- 850 -------------


 ------------- 800 ---------


This is NOT CORRECT:

  -------------  006 ---------

--------- 850 -------------


 ------------- 008 ---------


which means that it is enough to see only one contour line label and you
know where is up and where is down, i.e. if we have one contour line
like:

                               the label "800" means - this is higher

   ------ 800 ---------

                               the label "800" means - and this is lower



Does anybody have an idea how to do this labeling in mapserver?
