I've read rfc6110 and I didn't see any mention of "WHEN" on the mandatory status (section 9.1.1 Optional and Mandatory Nodes doesn't list it which seems a bit odd to me). The section on "WHEN" just mentions the xpath mapping, not anything about changing the mandatory status of the enclosing node.
I still think that the YANG RFC wording of "conditional" needs to indicate if the node is mandatory status is affected or not. Note that rfc6060 "3.1 Mandatory Nodes" doesn't mention "WHEN" (it does mention presence).
