While testing, I found that this model won't pass Domain.Build (4.3 Release, Recreate mode)

public class SampleProcessor : QueueProcessor
  {
    [Field]
    [Association(PairTo = "Owner", OnOwnerRemove = OnRemoveAction.Cascade, OnTargetRemove = OnRemoveAction.Clear)]
    private EntitySet<PersistentString> SampleStringList { get; set; }
  }

  [HierarchyRoot]
  public class PersistentString : Entity
  {
    [Field, Key]
    public long Id { get; private set; }

    [Field]
    public string Value { get; set; }

    [Field]
    public SampleProcessor Owner { get; set; }
  }

  public class QueueProcessor
  {

  }

  [HierarchyRoot]
  public abstract class Processor : Entity
  {
    [Field, Key]
    public long Id { get; private set; }
  }

This is not a big issue for us, but I thought I'll let you know.

Are you sure? I've defined only public class in this sample.
