Deprecated in CityGML version 0.4.0. Use the concepts of the new appearance model instead.
A property that has an _Appearance as its value domain, which can
either be a Material (Color,...) or a Texture. The _Appearance Element can either
be encapsulated in an element of this type or an XLink reference to a remote
_Appearance element (where remote includes geometry elements located elsewhere in
the same document). Either the reference or the contained element must be given, but
neither both nor none.
The side of the surface the _Appearance refers to is given by the orientation attribute,
which refers to the corresponding sign attribute of the orientable surface:
+ means the side with positive orientation, and - the side with negative orientation.
