typedef for generators

NHibernate 2.1.0Beta1 has another facility for your needs.

Now the <typedef> can be used even for generators:

<typedef name="HighLow" class="NHibernate.Id.TableHiLoGenerator, NHibernate">
   <param name="max_lo">99</param>
</typedef>

<class name="EntityCustomId">
   <id name="Id">
       <generator class="HighLow"/>
   </id>
   <property name="Name"/>
</class>

Only as a reminder the <typedef> tag can be used for any other type definition (properties and collections types).
