Assume a Government Street Lamp Bureau file has these types:
Ornamental pole Metal pole Concrete pole
Well wouldn't it make more sense for me to use
support=pole pole:type=ornamental pole:type=metal pole:type=concrete
Wall_mount usually just means 'Attached'
Note that a "wall mount" could be attached to a wall, pole, etc. It is the same mounting bracket with four screws, etc. no matter if it is attached to a wall in the city, or a pole in the country. Better to use Key:support if more information is known, no? Jidanni (talk) 01:31, 28 July 2017 (UTC)
