[openrailwaymap] Tag railway=station on ways and Wiki

Hi guys, (sorry for the crossposting) Yesterday I noticed a little misalignement between the wiki and the tags currently used by mappers. The wiki [0] suggests to use the tag "railway=station" on nodes only but taginfo [1] shows that there are 8120 way with that tag (and 515 relations too). We are used to say "no automated edits" and "always discuss with other mappers" so i just asked the dumb question «may I change them in Italy accordingly to the wiki?» in my local mailing list [2]. Seeing that the topic is not limited in my country, another mapper asked the same question (yeah, not really the same, but somehow related) on the tagging mailing list [3]. Two hours later someone edited [4] the wiki page removing the difference between a station and a halt, writing that the difference is only in German speaking countries (of course it's false: English has station/halt, Italian has stazione/fermata, French has gare/halte, ...) That sounds like vandalism for me. (He decided we shouldn't map reality?) We got some reactions in the Italian ML: some mappers agree with putting the tag on a node, someone like it more on ways (even buildings), other guys like relations. Other question that came up was "why is it so important for that node to be unconnected with the railway track?" Now you know my story. Can someone help me to know exactly why it's better tagging a "railway=station" with a node only? I mean I need to have a two-line sentence to add to the wiki (tag:railway=station) for those (the majority of the guys out there) who didn't read the bible [5]. Any advice (answers, discussions, questions, doubts, ... even insults) are welcome, let me know your point of view. Thank you in advance. Mauro.
