<choice[N]> [text] </choice[N]>
Occurs: Only inside choicePanel
Multiple instances: Yes - within each choicePanel
Has attributes: No - but should enclose a text string
Self-closing: No
This tag sets the radio button choices in a choicePanel, where 'N' is the number of the choice, e.g. 'choice1', 'choice2', etc. If the choicePanel offers a different image for each choice selected then numbered pic tags should be used. To show only a single, unchanging, image on the panel use picture instead or omit pic/picture altogether for no image.
The default choice is set via a (previously) Set variable. If no choice is pre-set, the default is choice1.
Example:
<choice2>green</choice2>
