NHibernate lazy loading part of a map

Question

Hi all,

I was wondering if there is any way to lazy load part of map in NH?

Here is my mapping:

<map name="Resources" table="COUNTRY_TL" fetch="subselect">
  <cache region="CountryCache" usage="read-write" include="all"/>
  <key column="COUNTRY_ID"/>
  <index column="LANGUAGE_CODE" type="System.String"></index>
  <composite-element class="Country+Translation">
    <property name="Name" column="NAME" />
  </composite-element>
</map>

The map itself is lazy loaded already by setting fetch to "subselect". I am wondering if there is a method to lazy load the map value (the composite element in this case) by specifying a index?

Thanks in advance.
