23 | * The do element provides a general mechanism for the user to act upon the current card, in other | |
24 | * words a card-level user interface element. The representation of the do element is user agent | |
25 | * dependent and the author must only assume that the element is mapped to a unique user interface | |
26 | * widget that the user can activate. For example, the widget mapping may be to a graphically | |
27 | * rendered button, a soft or function key, a voice-activated command sequence, or any other | |
28 | * interface that has a simple "activate" operation with no inter-operation persistent state. The do | |
29 | * element may appear at both the card and deck-level. | |
