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).
The ViewVersion and NodeVersion Properties do not change due to the publication of a SemanticChangeEvent.
SemanticChangeEvents are handled in the context of a View the same way as ModelChangeEvents. This is defined in 9.32.3.
SemanticChangeEvents can be compressed the same way as ModelChangeEvents. This is defined in 9.32.4.
