title: Rest Multiple parentId id's
body: <p>I have a rest resource with the uri:</p>
  
  <pre><code>/invoices/1/invoiceitems/34
  </code></pre>
  
  <p>Now I have to add a child of invoice items called invoiceitempieces</p>
  
  <p>Should this be done like this:</p>
  
  <pre><code>/invoices/1/invoiceitems/34/invoiceitempieces/7
  </code></pre>
  
  <p>That seems more organized than these options</p>
  
  <pre><code>/invoiceitems/34/invoiceitempieces/7
  /invoiceitempieces/7
  </code></pre>
  
  <p>I prefer the example with all three IDs but is that best/acceptable practice?</p>
