@facingDirection of roadSideLights is missing in the tree

Background

@facingDirection of roadSideLight is in the schema but not in XML tree.

Solution

Modeling should be fixed.

Documentation: "indicates the orientation of the lights as seen by road user". We distinguish two options: either the light is standing behind the crossed rails facing "towardsRail" or the light is standing before the crossed rails facing "awayFromRail".
