<instance>
    <data xmlns="">
       <choice>one two four five</choice>
    </data>
</instance>

<select ref="choice" selection="open">
    <item><label>Un</label><value>one</value>
    <item><label>Deux</label><value>two</value>
    <item><label>Trois</label><value>three</value>
</select>

What is displayed initially? This?

[x] Un
[x] Deux
[ ] Trois
[x] four
[x] five


(Current spec says the values are "retained", but says nothing about  
displaying)
