Orbeon Forms 2020.1
Features
XForms 2.0 features added with Orbeon Forms 2020.1:
xf:copy
Orbeon Forms implements XForms 2.0 enhancements to xf:copy including support for:
xf:item
attributes and other node types
XPath 2
NOTE: While xf:copy is an XForms 1.0 feature, Orbeon Forms didn't support it until version 2020.1.
Example of xf:copy attributes support
Let's say we an XML representation which proposes a discriminated union based on a type attribute. We have, in the data, either:
<label type="PredefinedButtonLabel"/>
or:
<label type="CustomButtonLabel">
    <name type="object">
        <values type="object">
            <en>Custom Button</en>
        </values>
    </name>
</label>
With xf:copy, the selection is written as follows:
<xf:select1 ref="label" appearance="full">
    <xf:item>
        <xf:label>Predefined</xf:label>
        <xf:copy ref="xf:attribute('type', 'PredefinedButtonLabel')"/>
    </xf:item>
    <xf:item>
        <xf:label>Custom</xf:label>
        <xf:copy
            ref="
                xf:attribute('type', 'CustomButtonLabel'),
                if (@type = 'CustomButtonLabel') then
                    *
                else
                    instance('my-custom-button-label-template')"/>
    </xf:item>
</xf:select1>
<xf:input ref="label/name/values/en"/>
The if ... then ... else pattern in the second xf:copy is there so that, in case the user has already selected a CustomButtonLabel and edited the value of the button label (here "Custom Button" initially), there will still be an exact match and the item shows as selected.
