I would like to unmount the following xml in MultiKeyMap :
<map>
<entry key1="foo" key2="foo">
<value property="val"/>
</entry>
<entry key1="bar" key2="bar">
<value property="val"/>
</entry>
</map>
I looked at the Castor API and saw that there was a CollectionFieldHandler class , but I could not find documentation about where I would need to register a custom collection handler.
