When an entity with an IdClass is mapped using XML ORM descriptors,
Hibernate requires the Id properties to be mapped as well, as in the
following example:
<entity class="Employee">
<table name="entityobject"/>
<id-class class="EmployeeId"/>
<attributes>
<id name="fname"/>
<id name="lname"/>
</attributes>
</entity>
If the <id> elements are not included, an exception is thrown:
"No identifier specified for entity: ..."
Should Hibernate require the <id> elements to be explicitly mapped, or
should it be able to determine this information by reflection from the
class configured by <id-class>?
