property state

For an attribute with basic data type the property state is represened by an attribute value. For a base structure or an attribute with complex data type the property state is the combination of all property values of the complex data type.

For a collection property, the property state is defined by the instances stored in the collection. Adding or removing will change the property state.

An exception in ODABA are memo and blob properties, which are, physically references, but conceptually considered as attributes.
