.:: Mapping a Map

Hi all!
I'm trying to create a map, but I'm having some problems when compiling my hibernate mapping file.

Here are my classes:

Code:

public class ClientType
{
   private Long code;
   private String name;
   
   private Map tariffs;

// getters and setters....

}

this object will have an Map of tariffs as you can see, so these will be the classes regarding Tariffs:

Code:

public abstract class Tariff
{
   private ClientType clientType;
   private Calendar fromDate;
   private String name;
   private double markUp;
   
   private TariffID id;

// getters and setters...
}

public class TariffID implements Serializable
{
   private ClientType clientType;
   private Calendar fromDate;

// getters and setters, equals() and hashChode()
}

Now, what I'm trying to do to map this is:

Code:

<class name="es.agency.ClientType">
   <id name="code" type="long" column="code"  unsaved-value="null">
      <generator class="native"/>
   </id>
   <property name="name" type="string" length="40"/>
   <map name="tariffs" inverse="true" lazy="true" cascade="all">       
      <key column="clientType"/> 
       <index column="fromDate" type="date"/>       
      <one-to-many class="es.tariff.Tariff"/> 
   </map> 
</class>


<class name="es.tariff.Tariff" discriminator-value="U">
    <composite-id name="id" class="es.tariff.TariffID">
       <key-many-to-one name="clientType" class="es.agency.ClientType" column="clientType"/>
       <key-property name="fromDate" type="date"/>
   </composite-id>
   <discriminator column="type" type="character" />
   <property name="name" type="string"/>
   <property name="markUp" type="double"/>   
   
   <subclass name="es.tariff.NetTariff" 
       discriminator-value="N" dynamic-update="true"
       dynamic-insert="true">
    </subclass>
    
    <subclass name="es.tariff.CommissionableTariff" 
       discriminator-value="C" dynamic-update="true"
       dynamic-insert="true">
       <property name="commission" type="double"/>
    </subclass>   
</class>

but when compiling I'm getting errors like:

Code:

0    [main] ERROR net.sf.hibernate.util.XMLHelper  - Error parsing XML: XML Inpu
tStream(306)
org.xml.sax.SAXParseException: The content of element type "map" must match "(me
ta*,jcs-cache?,key,(index|composite-index|index-many-to-many|index-many-to-any),
(element|one-to-many|many-to-many|composite-element|many-to-any))".

So how should I map the ClientType, so it can have a tariffs map?
Thank you very much in advance!!!

Try the xml parser provided in the Hibernate distro

ok, but I just need to know the syntax for the <map></map> of tariffs, knowing that the primary key of a tariffs has two elements, which are a clientType and a date.
Thank's in advance!!

It is the expected syntax.
The FK is a 1-column key (clientType).
