You propose to use semicolons to separate the values if the cables at a mast have a different suspension: line_attachment=suspension_clamp;pin;suspension_clamp We have a similar issue when tagging different speed limits on road lanes and use a | to separate lanes (minspeed:lanes=90|90|40). Unfortunately, the cables of a power line can be located on multiple levels. Therefore, you propose to use semicolons to separate cables at the same level and vertical bars to separate levels. A semicolon has a slightly different meaning in OSM. I would like to see line_attachment=* only for masts where all cables are mounted equally and propose to use line_attachment:cables=* if one value does not fit all cables. In order to circumvent the semicolon issue, I propose to introduce round braces for all cables of one level. https://wiki.openstreetmap.org/wiki/File:Pole_multi_attachement.png would be tagged like this: line_attachment:cables=(suspension_clamp|pin|suspension_clamp)|(suspension_clamp) This avoids using adding variable parts into keys (line_attachment:1=*, …) which I myself could not call "good tag design".
