Return ValueType: String
A String that contains the expression used to evaluate the property.
The following example sets the Description property of the log provider to be the text, "This is the log for…" with the current month and day appended to the end of the string. It then validates the package, which resolves the expression and saves the value to the property specified in propertyName. The expression will also be set on the expressions on the property when the package is saved.
Current description: Writes log entries for events to a CSV file
Validation passed: Success
The expression for Description is "This is the log for January 06"
