Edge between Edges

[LeStef]

This is a more general question. Is there a way to create an edge between two edges, or between a node and an edge?

a minimal example:
node1 = "height of Mt. Everest", node2 = "height of Mt. Blanc", node3 = "air density on Mt. Everest", node4 = "air density on Mt. Blanc"
edge1 (node1 -> node2) = "is greater than", edge2 (node3 -> node4) = "is smaller than"

and now edge between edges:
edge3 (edge1 -> edge2) = "thats why"

Hi,
It's not possible to create edges between edges.
