I found a typo in the osmarules, lines 900 and 903: <rule e="way" k="constuction" v="steps"> <line class='highway-core highway-steps-core under-construction' /> </rule> <rule e="way" k="constuction" v="footway|footpath"> it should be construction instead of constuction. (if I knew what a footpath in construction would be ;-) ) Martin
