title: How to find if a referenced object can be deleted?
body: <p>I have an object called "Customer" which will be used in the other tables as foreign keys. </p>
  
  <p>The problem is that I want to know if a "Customer" can be deleted (ie, it is not being referenced in any other tables).</p>
  
  <p>Is this possible with Nhibernate?</p>
