[Description] This attribute can mean two different things, it depends on the presence of the verifyproperty attribute. If you don't set the verifyproperty attribute, property specifies the name of the property to be set with the generated checksum value. If you set the verifyproperty attribute, property specifies the checksum you expect to be generated (the checksum itself, not a name of a property containing the checksum). This cannot be specified when fileext is being used or when the number of files for which checksums is to be generated is greater than 1. [Required] No [Attribute]
