Sorry, I didn't realize that it's an ambiguously worded duplicate of the usage-paragraph. My main intention was to remove the parts, which said that noexit=yes should be used on ways (which were added by you). I thought there was sort of a consensus that it should not be tagged on ways, so I simply changed the page. I didn't want to start another large discussion like in March/April on Talk-de and Tagging (in which I both participated), because I think most of the points were discussed extensively there. > He restored the icons that I had restored myself to "node only" but > that Pieren had set to "node+way".

I wonder if all those gotchas are not > made on purpose. I can't find any sentence in your version, that is saying, that the tagging on ways "must *not* be done". It just said, that noexit=yes can be tagged on ways and/or on nodes. In my opinion the main purpose of the wiki is not to document tagging trends, but best practices for tagging. I don't see the necessity for adding a sentence stating that in the past it was used on ways, but if you see this necessity, feel free to add such a sentence. You are right, that the paragraph "When not to use" should mention the ways. Thus I've changed the page again and added a sentence to that paragraph, stating that usage on ways is discouraged. > > Well, I finally put this at the beginning: >> Read important warnings first, then read tag syntax in paragraph >> *Usage*. >> >> Do not use this tag on ways (only on nodes). >> > There's little excuses any more.
