The PropertyInformation object contains the meta-information of an individual property within the configuration. This object can be used when validating and changing the properties of an individual attribute.

The PropertyInformation object is derived from the associated PropertyInformationCollection object. The PropertyInformationCollection object is derived from the associated ElementInformation object.

The following code example demonstrates how to use the PropertyInformation type.
