Remarks
This method informs the base class that the property exists, but does not supply it with a value. The base class notes that no value has been provided and on first request calls the RetrieveValue method to obtain the value. Subsequent calls return a cached copy of the value, so RetrieveValue is not called again for this property.
This method should be called by derived classes, normally in their constructor, to indicate that a particular property is supported. Without calling this the Contains method returns false for this property name (unless it was already specified in one of the constructors).
