Boolean indicating that this card is physically unique from other cards of the same type and therefore requires a special slot. For example, a double-wide card requires two slots. Another example is where a certain card may be used for the same general function as other cards but requires a special slot (e.g., extra long), whereas the other cards can be placed in any available slot. If set to TRUE, then the corresponding property, RequirementsDescription, should specify the nature of the uniqueness or purpose of the card.
