title: How to prevent BSON deserialization instantiating members in a class?
body: <p>I have a class that instantiates it's own internal objects and changes internal properties on them which aren't serialized.  One for example is setting the parent object.  </p>
  
  <p>How do you prevent the BSON driver from instantiating these particular members on a class, since the main class for the document already does this?</p>
  
  <p>I have read the serialization information (quite minimal) and checked what BSON attributes are available but I don't see anything that looks like it will help.</p>
