Re: [Xsltforms-support] Binding to optional element

[Micah D. <Mic...@ma...>]

Thanks Tambet,

Looks like a good direction to pursue.

In the case where the default selection (no element) gets saved and then the form is reopened, in other words when the instance is
<root/>

How do you make it work (since the binding to /root/format goes nowhere)?
