title: Mapping records to specific path in EMT when node names are duplicated
body: <p>We have an Externally Managed Taxonomy (EMT) and have been using a node's name to map records to the hierarchy. We are now hitting a problem because some of the node names in the hierarchy are duplicated.  Ids are used to make the nodes in the EMT unique, but I haven't found documentation on how to use something other than name to map a record. For example, how do I map a records to child_2 below, rather than child_1 if both are named "A child"?</p>
  
  <pre><code>Root [id=root]
  |-One parent @id=parent_1 @parent=root
  |   '- A child @id=child_1 @parent=parent_1
  '-Other parent @id=parent_2 @parent=root
      '- A child @id=child 2 @parent=parent_2
  </code></pre>
