Re: ACTION-2234: Spec up changes to load.

As part of this action, I identified other elements that have a @ref plus  
other possible expressions, that would be evaluated in the context of the  
ref.

(I have omitted deprecated elements).

* select/item/value
  <select ...>
     <item>
        <label>...</label>
        <value ref="..." value="..."/>
     </item>

* select/itemset
  <select ...>
     <itemset ref="..." copy="...">

* submission
  <submission ref="..." targetref="..." lots of others
  @targetref is evaluated in the in-scope context

* <repeat ref="..." indexref="..." startindex="..." number="...">
   @indexref is evaluated in the in-scope context.

* submission/header
   <submission ...>
       <header ref="..." name="..." value="..."/>

ACTIONS

* <setvalue ref=".." value="..."/>
* <load ref="..." resource="..."/>
* <message ref="..." value="..."/>
* <insert ref="..." at="..." origin="..."/> @origin is evaluated in the  
in-scope context
* <delete ref="..." at="..."/>
