having more than one main tag on an object is in my opinion
a practice not to be encougered, it's again one feature = one object: 
you add the information that it is made of aluminum or yellow color... 
what does it refer to? the pole? the lamp?

highway=street_lamp support=pole + power=pole seems better to me. 
moreover their geometry is not necessarily the same (if we reduce
the lamp to a point, the most logical is to put this point in
the center of the lamp, not on the outside of its pole)

Regards,
Marc
