SemanticChangeEvents are Events of SemanticChangeEventType that are generated to indicate a change of the AddressSpace semantics. The change consists of a change to the Value Attribute of a Property.

The SemanticChangeEvent contains information about the Node owning the Property that was changed. If this is a Variable or Object, the TypeDefinitionNode is also present.

The SemanticChange bit of the AccessLevel Attribute of a Property indicates whether changes of the Property value are considered for SemanticChangeEvents (see 5.6.2).
