filter tags by numerical values
(possible) syntax: key < value
, key > value
, …
example: lanes >= 2
to clarify:
- what selector should do if the tag is not present? intuitively, neither
lanes >= 2
norlanes < 2
should not match a building. but shouldn't the selectors be complementary i.e.lanes >= 2 or lanes < 2
should match everything (likelanes = 2 or lanes != 2
matches everything)?!
