The ICEAttribute object represents an attribute data set (a collection of information used in the ICE system, such as Age, PointPosition, NbrPolygons, etc.).
Attribute data sets belong to scene objects such as geometries and properties. Some attributes are built-in, others may be user-defined. ICEAttribute objects can be accessed through Geometry::GetICEAttributes and ProjectItem::GetICEAttributes.
