That should be possible, I think:
Let's assume the SRTM is preprocessed to contain the contour-lines as
Then each line has as an attribute it's elevation level.
With MapCSS you can set these lines as visible, e.g. printed as a thin
black line - easy so far.
I'm not sure, but I think, it should be possible to check in some kind
the elevation value with conditions in the selector, e.g.
Currently as far as I can see these more complex selectors are not
implemented in Kothic, but I think, you are welcome to do that ;)
In general MapCSS should support these kind of of selectors, I think.
