Again thank you. I'll start work on updating the tags for these nodes.

The "TowerX" value is not present on the mast and I believe it is just an identifier used by the EFF for these deployments, so from your comment it seems like I should use unsigned_ref:US:eff=*.  To correct these nodes, would you suggest I update the attribute tag to be "source=*" and then also use "source:unsigned_ref:US:eff=*" or simply use the top level unsigned_ref key like "unsigned_ref:US:eff=*"?  The intention of source:eff_ref was to specify what identifier in the original dataset references this node so it can be validated and/or updated if the location or attributes of the deployment ever changes.
