Use Input Source

When this option is selected for an attribute, the object reads the attribute data from the I/O reference.

The I/O qualities of the attribute are as follows:

Good

Specifies no errors while the object reads the data for an attribute from the I/O reference.

Bad

Specifies error such as invalid reference, invalid data type conversion, or a failure in reading I/O data for unknown reason, which occur while the object reads the data for an attribute from the I/O reference.

When this option is not selected for an attribute, no action occurs if the previous state of the attribute is already set to False.
