title: eBay API setting Child Categories Doesn't work
body: <p>I'm asking here and not on eBay forums because no one seems to ever respond or is active there.</p>
  
  <p>Basically I'm using the SetStoreCategories method on the Trading API.
  <a href="http://developer.ebay.com/DevZone/XML/docs/Reference/eBay/SetStoreCategories.html" rel="nofollow">http://developer.ebay.com/DevZone/XML/docs/Reference/eBay/SetStoreCategories.html</a></p>
  
  <p>My data part of the API call is as follows</p>
  
  <pre><code>&lt;Action&gt;Add&lt;/Action&gt;
  &lt;StoreCategories&gt;
    &lt;CustomCategory&gt;
       &lt;Name&gt;name of a thing&lt;/Name&gt;
       &lt;ChildCategory&gt;
          &lt;Name&gt;a child name&lt;/Name&gt;
       &lt;/ChildCategory&gt;
    &lt;/CustomCategory&gt;
    &lt;CustomCategory&gt;
       &lt;Name&gt;name of another thing&lt;/Name&gt;
       &lt;ChildCategory&gt;
          &lt;Name&gt;2nd child name&lt;/Name&gt;
       &lt;/ChildCategory&gt;
    &lt;/CustomCategory&gt;
  </code></pre>
  
  <p></p>
  
  <p>And the eBay API result is</p>
  
  <pre><code>array(7) {
    ["Timestamp"]=&gt;
    string(24) "2013-07-15T01:49:39.888Z"
    ["Ack"]=&gt;
    string(7) "Success"
    ["Version"]=&gt;
    string(3) "831"
    ["Build"]=&gt;
    string(32) "E831_CORE_APISELLING_16205050_R1"
    ["TaskID"]=&gt;
    string(1) "0"
    ["Status"]=&gt;
    string(8) "Complete"
    ["CustomCategory"]=&gt;
    array(1) {
      ["CustomCategory"]=&gt;
      array(2) {
        [0]=&gt;
        array(2) {
          ["CategoryID"]=&gt;
          string(9) "660835819"
          ["Name"]=&gt;
          string(15) "name of a thing"
        }
        [1]=&gt;
        array(2) {
          ["CategoryID"]=&gt;
          string(9) "660835919"
          ["Name"]=&gt;
          string(21) "name of another thing"
        }
      }
    }
  }

  <p>So you can see that it's not looking at my child categories. I've check on ebay.com and they aren't there.</p>
  
  <p>The ebay api says that a CustomCategory element is the same type as a ChildCategory type. And you can only nest 3 children in. But I can't even get 1 to nest.</p>
  
  <p>Any help would be amazing.</p>
  
  <p>Thanks!</p>
