Hi.
If you are right (and yes, that's possible, I can't prove the opposite),
I think this should be stated clearly in the documentation.
On the other hand I'm not sure if this variant is really the best idea.
It leads to verbose, hard do maintain mapcss stylesheets if the
developer wants to set up a fixed rendering order, and usually at maps
that's the case for most rules, I think.
I would change it in the wiki, but I would like to get more comments on
that from the list, so I don't change it now.
regards (and thanks for the answer)

At least in my interpretation of MapCSS, the behaviour when two
objects are defined to have the same z-index is undefined. The order
of rendering here should (in my book) be effectively random.

Hi.
I have to give a short introduction to someone who should implement a
mapcss renderer and looked into the docs availlable for that.
For that I especially looked into the sotm-eu presentation done by
Maskim [1], and I fear there is a small bug on slide 7 (and the
following pages).
The stylesheet presented does not contain any z-index or layer
definitions. To quote the slide, it's defined as:
line[highway] {
color: orange;
width: 11;
}
area[building] {
fill-color: gray;
}
line[waterway] {
color: blue;
width:3;
}
The image presented nearby shows a similar image, but the highway is
rendered on top of the river.
Shouldn't that be the other way around (according to the mapcss code,
not to "good maps")?
