I would consider those tags on nodes as broken. These should all be way tags. I would propose to change Map Features in this respect and have the JOSM Validator, Maplint & Co. put warnings on nodes where they exist. An incline that "fits" into a node is either so low that it is not worth tagging at all or is so steep that it should better be tagged as cliff. ;-) Actually highway=incline[_steep] should be discouraged alltogether. http://wiki.openstreetmap.org/wiki/Key:incline mentions incline=up and incline=down for cases when the exact value is not known. Also, inline=* can be used for other things beside highways. > > You are right in saying that this is ambiguous in theory.

Even in the case where the node simply connects two ways there is a problem if one of them gets reversed. > > I don't even known if JOSM handles this correctly at the moment, but if > it does then it should perhaps not be broken? JOSM currently looks for left/right, forward/backward, forwards/backwards and oneway tags, values and relation roles. There is no reversal for highway=incline. All JOSM could do is put out a warning. It certainly makes sense to include incline=* - most of which are on ways anyway (according to OSMdoc).
