Description
Target Attribute: a custom attribute.
Purpose: Create a reference to an EL expression that can be used in another EL expression.
We have to create this binding on a component's custom attribute whose name is referred in another EL expression. The EL expression that refers to the reference must be the children of the component that has the reference binding. It is useful to shorten an EL expression and be referred by another expression.
Example
<div p="@ref(vm.selectedPerson)"/>
<label value="@load(p.id)" />
<label value="@load(p.name)" />
</div>
