itemset and value

While looking at examples to change label elements to attributes, I came  
across this example in  
https://www.w3.org/community/xformsusers/wiki/XForms_2.0#Instance_Data

  <select1 ref="land">
    <label>Country</label>
    <itemset ref="instance('c')/country">
      <label ref="."/>
      <value ref="@code"/>
    </itemset>
  </select1>


If I look at the definition of itemset, to my surprise @value is not an  
available attribute, yet I would expect to be able to write:

  <select1 ref="land" label="Country">
    <itemset ref="instance('c')/country" label="{.}" value="@code"/>
  </select1>

(and the same with <copy> by the way).

Is this an oversight, or is there a reason?
