title: Not able to fetch "Name" of lookup fields of Link-Entity (Web API + FetchXml)
body: <p>I have some fetchXml that I am executing through the Dynamics CRM Web API.  THe fetchXml query is constructed like so:</p>
  
  <pre><code>&lt;fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false"&gt;
    &lt;entity name="new_someEntityA"&gt;
      &lt;attribute name="new_lookupForSomeEntityA" /&gt;
    &lt;link-entity alias="new_someEntityB" name="new_someEntityB" from="entityBId" to="entityAId" visible="false" link-type="outer"&gt;
      &lt;attribute name="new_lookupForSomeEntityB" /&gt;
    &lt;/link-entity&gt;
    &lt;/entity&gt;
  &lt;/fetch&gt;
  </code></pre>
  
  <p>When I send this query through the Web API, I get a response and the value for "new_lookupForSomeEntityA" includes the value (GUID) and a Formatted Value (it's name).  But the response for "new_lookupForSomeEntityB" includes just the GUID and I can't find a way to get it's GUID and value.  I've added a header record for: </p>
  
  <pre><code>"Prefer": "odata.include-annotations=OData.Community.Display.V1.FormattedValue"
  </code></pre>
  
  <p>but that appears to just get me formatted values for the primary entity and not the link entity.  Is this a limitation of the Web API or am I doing something wrong?  Any help would be appreciated.</p>
