I should be using the default. Here is one of the smaller mapping files:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
  <class name="Com.Klinitek.Census.Shared.Model.Location, Com.Klinitek.Census.Shared" table="Location">
    <id name="Id" column="id_location" type="System.Int32">
      <generator class="identity"/>
    </id>
    <property name="PointOfCare" column="point_of_care" type="System.String" not-null="true"/>
    <property name="Room" column="room" type="System.String" not-null="false"/>
    <property name="Bed" column="bed" type="System.String" not-null="false"/>
    <property name="Description" column="description" type="System.String" not-null="false"/>
    <many-to-one name="Type" column="type_code" 
                  class="Com.Klinitek.Census.Shared.Model.LocationType, Com.Klinitek.Census.Shared" cascade="none" not-null="true"/>
    <many-to-one name="Status" column="status_code" 
                 class="Com.Klinitek.Census.Shared.Model.LocationStatus, Com.Klinitek.Census.Shared" cascade="none" not-null="false"/>
    <property name="IsSwing" column="swing_bed" type="System.Boolean" not-null="false"/>
    <property name="DateCreated" column="date_created" type="System.DateTime" not-null="true"/>
    <property name="DateLastModified" column="last_modified" type="System.DateTime" not-null="true"/>
    <property name="IsActive" column="active" type="System.Boolean" not-null="true"/>
  </class>
</hibernate-mapping>
