title: Fluent NHibernate One-To-One with only one foreign column
body: <p>I have 2 one-to-one tables in my db, and only one of them has foreign key to another table.
  Here is an example of what I have</p>
  
  <p>Table 1: <strong>Container</strong><br>
   - Id (PK)</p>
  
  <p>Table 2: <strong>Item</strong><br>
  - Id (PK)<br>
  - ContainerId (FK)</p>
  
  <p>Can I configure their relations as one to one to have following models mapped:</p>
  
  <pre><code>public class Container{
       public virtual int Id {get;set;}
       public virtual Item Item {get;set;}
  }
  
  public class Item{
       public virtual int Id {get;set;}
       public virtual Container {get;set;}
  }
  </code></pre>
  
  <p>I can configure <em>Item</em> to have one <em>Container,</em> because it has explicit column for this, but how it can be done for <em>Container</em>?</p>
  
  <p>Thanks!</p>
