Well, it's really a composites of motion-isn't it?!
The spin is incorporated in with the revolution.
Relative to our central Sun, the Moon does have a spin, but it can only come as a result of the Moons movement around the Earth; like Parallel Transport in GR which I mentioned earlier. Relative to the Moon, it would appear to have genuine spin.
But wait, there's more! An object in orbit should maintain it's orientation to the central mass, ie, the nose of a space shuttle if pointing toward Earth will remain pointed toward Earth because the geodestic pathway curves around the Earth, and the geodesic runs tangental to the curve. This is the conservation of angular momentum being conserved with the geodesic itself...or Newtons third law conserved with the curvature of spacetime...cool hey?!
