Hi Manny, the purpose of the component diagram is to give an overview of components and their interaction. Generally, it's not the place to document single classes. I would rather put the transfer object into the class diagram. If you absolutely want to mention the TO in the component diagram, I would do it in a comment, e.g. "Transfer objects transport data across tiers".
Please note that this is my opinion, and I am not yet certified.
Putting this comment "Transfer objects transport data across tiers" would surely be nice. Thanks!
