Remarks

AutomationElementIdentifiers contains static defined values for various automation property identifiers that are common to the overall UI automation system. These property identifiers are of type AutomationProperty. Because AutomationProperty cannot be constructed by your code, automation property identifiers are obtained by getting the static values of this class, or from similar classes that identify the automation properties of specific provider patterns. In Silverlight UI automation, an AutomationProperty has no accessible properties, so the only usages are as a pure identifier. Specifically, a Silverlight UI automation AutomationProperty does not have an ID property.

You also use AutomationElementIdentifiers values(or specific provider automation property identifiers) in order to identify the specific automation property that changed when you call RaisePropertyChangedEvent.
