The MeshPrimitive represents a collection of polygonal faces. The faces should be planar and may not have holes, but can have concavities. By default a polygon is considered frontfacing if it's vertices wind in an anticlockwise direction from the point of view of the camera - this can be changed at the point of rendering by setting attributes in the Renderer. This definition of winding order is the same as the OpenGL and Maya conventions but the opposite of RenderMan's.
