title: Delete all related OData entities in one request from client
body: <p>To use the Northwind database as an example, each Customer has a collection of Orders. I would like to remove all of the references between a particular Customer and all their Orders in just one request.</p>
  
  <p>It looks like I can do this (based on the <a href="http://docs.oasis-open.org/odata/odata/v4.0/os/part2-url-conventions/odata-v4.0-os-part2-url-conventions.html#_Toc372793779" rel="nofollow">spec</a>) with <code>DELETE http://services.odata.org/V4/Northwind/Northwind.svc/Customers('ANTON')/Orders</code> but I'm wondering if client libraries support this. </p>
  
  <p>I'm using Microsoft.OData.Client for a C# client library, Apache Olingo (v4) for Java, and BreezeJS for JavaScript.  An example in any of these would be much appreciated.</p>
  
  <p>EDIT: Clarified that I am just removing <em>references</em>, not actually deleting the entities themselves.</p>
