title: Map to Serializable in Fluent NHibernate
body: <p>NHibernate has a "Serializable" type</p>
  
  <pre><code>&lt;property name="PropertyName" column="ColumnName" type="**Serializable**"  /&gt;
  </code></pre>
  
  <p>Is there a built in type for this in Fluent NHibernate?</p>
  
  <p>Something like</p>
  
  <pre><code>Map(x =&gt; x.PropertyName).CustomType&lt;**SerializableType**&gt;();
  </code></pre>
  
  <p>??</p>
