tiles and grids url token format?

[yhahn]

Is there a reason why the tiles and grids urls use a ${z} style token for replacement?

Out of the box, it looks like modest maps uses {Z} while leaflet uses {z}.

• http://leaflet.cloudmade.com/examples/quick-start.html

Wondering if we should switch and maybe come to a consensus on the right token to use.

I initially used %z, but @tmcw tipped me off that {z} is more common. I messed up the update and used ${z} instead. We should change it to {z}.

Ok, and lowercase? I think I tried {z} with modestmaps and it didn't work... needed {Z}.

[kkaefer]

We can make it /\{z\}/gi

[tmcw]

Leaflet uses {z}, Modest Maps uses {Z}, and OpenLayers uses ${z}.

/\$?\{z\}/gi?

Let's talk about this briefly today and decide on what the spec will use.

decided: {z}
