To help me understand, below are three schemes for crossings. Which one(s) best describe your suggested way of mapping.

1. Tagging both the crossing and a node on the highway. https://mycloud.snowandsnow.us/index.php/s/YEFoYcTgR2gtW3j
2. With no crossing ways, just a node on the highway to mark the type of crossing https://mycloud.snowandsnow.us/index.php/s/4ad5wLzMNcE3sNo
3. With just crossing ways and no node at the intersection of the crossing and highway. https://mycloud.snowandsnow.us/index.php/s/tHF62pH5txPEX55


Well, since you asked, as to my own personal preference, 

#1 is not my preference. Crossing tags are placed on the way and on a node for a single pedestrian crosswalk. I feel this violates OSM's "one feature, one OSM element" rule.
#2 seems acceptable, but it's not my personal preference. (Again, I started this thread not in order to express my preferences, simply to have the wiki compliant with approved OSM canon)
#3 has no connecting node between the two ways represented by the red dot? This would not be correct. There should be a connecting node.

This is an example of how I prefer to map pedestrian crossings (this is common throughout downtown Denver):

Here are two methods I mapped as a demonstration of mapping that I feel is correct, as well. Mapped here are two different methods that seem reasonable, tagging either the connecting node or tagging the way; but not tagging both the node and the way. Tagging both the node and the way would seem to violate the  "one feature, one OSM element" rule.
