Not sure what you are refering to, as I made a number of changes in this change set. If you mean the course of l'Elnon: I used the BD Carthage layer in JOSM. Please check also the note that I added in the relation. If you meant something else, please give me a specific way as an example.

Sinn und Verstand sind unter "source" des changesets angegeben. Aber es ist schön zu hören, dass jemand lokales Wissen hat, um den Sinn und Verstand der externen Quellen mit der Realität abzugleichen.

Hallo, ich hoffe, dass das jetzt alle waren. Habe das Problem auch an den anderen Stellen gefixed.

Thanks for pointing this out. Was a typo. I've just changed all 6 occurences to highway=footway

Hi Stereo, thanks for pointing this out. French wikipedia is not specific about the Chiers' spring, so I did not notice the "real" upper section. I have now seen, that there is a bit more in the Luxemburg Wikipedia. I added the section. In general, waterways are tagged as relation of the various pieces so that you can see/select/work on a river in its entirety
