Key:noref

Typically used as noref=yes to explicitly state that there exists no meaningful value for ref=* for an object.

For example: For unnumbered highway exits highway=motorway_junction (e.g. to rest areas) in highway systems where exits are normally numbered, use noref=yes to explicitly note that the ref=* tag is not missing, but rather that no such value exists for that node.
