What would happen if you changed the Attribute References parameter from 'Handle with Published Parameters' to its other possible value, 'Fix Manually (Advanced)'?

• A. The workspace won't run by default because no attributes are available in the custom transformer.
• B. There will be no way to pick attributes to use from the Main tab.
• C. The author will need to manually fix the custom transformer by exposing attributes in its definition.
• D. All of the above.

Answer: (D)

Attribute References determine how a custom transformer resolves attribute names inside it. When you choose to handle them with published parameters, the transformer exposes those attribute names as user-settable parameters, so you can pick which attributes to use from the Main tab, and the workspace can run with those attributes available by default. If you switch to fixing them manually, that automatic binding is removed. You won’t have a way to select attributes from the Main tab, and the author must explicitly expose and map attributes in the transformer’s definition. That means the workspace may not run as-is, there’s no automatic attribute selection, and the author must take a manual step to expose attributes. All of these conditions together explain why choosing the manual fix option leads to the combined outcome, making all of the above true.
