Thanks for the report, @dsietz. I'm going to wait until the schema is resolved per rust-lang/rust#49359 before I make more progress here.

Are you thinking we'd map "median" to the JUnit "duration"?

I think that would be a good mapping. But how would the deviation be mapped? The 2 attributes go hand in hand.
