MR> I do not know why anyone should tag one OSM way both with power=* and MR> railway=*.
and here I contradict my own oppinion: In many cities, there's a gas pipeline running under (almost) every street, providing gas to domestic homes (as do water, sewage ...) just imagine a city like vienna, drawing one or more man_made=pipeline ways parallel to nearly every highway=* - a nightmare, editing-wise. in these cases, it would be better to use the already existing highway=* way and also tag it as man_made=pipeline. and here we have the first name=*, ref=* conflict, only to be solved by prefixes. similar situations where pipelines run underneath bridges to cross a river (etc). can't speak for the power guys here, but rather unlikely that something runs directly underneath/above a high voltage power line ;-) cu _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
