I'm using a Java 5 enum as a key to a Map. Whenever I use an enum as a regular old property, I have used an inline type declaration such as:

<property name="imageType" column="TYPE">
<type name="EnumUserType"><param name="enumClassName">ImageType</param></type>
</property>

It would be nice to be able to do the same thing inside of <map-key> but the DTD doesn't seem to allow it. I had to use a <typedef> instead.


Hibernate version:
