IMG for <ZH>Classification</>.

for each object type. This identifies the object type in dependency
maintenance functions. 'Material' is the object ID for materials.

object type. The fields of the object key are referred to by a special
field identifier. The object key for materials is the material number.

The entries for this object are syntactically correct. However, they
are incomplete. This means that parts of the object key are missing.
