There are no speciallmade product attributes in the demo store and since it resets every 4th hours I skip making one, but I use the SONY DSC-T700(g) DIGITAL VIDEO CAMERA as an example.
Lets say the attributes are;
SKU:
Availability: In Stock
Quantity: 10 pcs
MegaPixels : 10,1
Memory : 4GB
Face Detection : Yes
As you can see there I linked the attribute to sites with explanations of what it means.
Could be to an extrenal site or one of the TomatoCarts own CMS pages.
Thats basicly my suggestion.
To give custommers a better service to understand what you sell and what it does.
