Yes, it could, but when querying data I would want to retrieve information that is given in words. Asking for all films that include Brad Pitt would be a search against words related to the video, not to the bytes in the video value. A list, on the other hand, should be able to give me answers to questions such as (in English) "give me all e-mail addresses for people that include their full last name in them", thereby recognizing that there are multiple values within this one attribute of e-mail address. --dawn
