Ah, already found out this syntax contained too many spaces 😉

barrier=* & barrier ~ '(lift_gate|toll_booth|border_control|swing_gate|log)' [0x3201 resolution 23]

This one works. Dont know if mkgmap ignored those spaces before though.

Hi,

I have noticed that this notation seems not to work anymore (I'm sure it worked before):

barrier=* & barrier ~ '(lift_gate | toll_booth | border_control | swing_gate | log)' [0x3201 resolution 23]

I have a lot like those lines in my style sheets and I dont know why pois like barrier=swing_gate is not catched by the line above anymore?

When I add barrier=swing_gate [0x3201 resolution 23] it works as expected.
