@Type with Maps from Element to Element applies to both key to value type.
--------------------------------------------------------------------------

                 Key: ANN-696
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-696
             Project: Hibernate Annotations
          Issue Type: Bug
          Components: binder
    Affects Versions: 3.3.0.ga
         Environment: Hibernate Annotations 3.3.0.ga, HSQLDB 1.8.0.7, JUnit 4.1
            Reporter: Timon Hertli
         Attachments: test.zip

Having a Hibernate map where key and value are both Elements, the @Type annotation seems to affect both key and value type:

@CollectionOfElements
@org.hibernate.annotations.MapKey
@Type(type = "myEnumType")
private Map<MyEnumType, String> enumKey = new HashMap<MyEnumType, String>();

@Test
void testEnumKey () {
	MyPc pc = new MyPc();
	pc.getEnumKey().put(MyEnumType.TYPE1, "str");
	session.saveOrUpdate(pc);
	session.flush(); //flush throws an exception since it tries to persist the String as "myEnumType"
}

I think the following should be the expected behaviour:
@Type should only affect the Map value type. 
There should be a seperate possibility to affect the key type with an @Type annotation, as it is the case with @Column now.
