Decision of xforms:select/select1 appearance's value

> Hi Erik,
>
> Thanks for the tips. Please see the workable version below. As you can see,

> single/multiple selection. Should be easily scaled up to cover appearance
> types compact and xxforms:autocomplete. It also generalizes the ref feed to
> itemset.
>
> There should be only scenario to make such effort worthy is when there are
> plenty of dropdown lists to be produced.
