In Hibernate: is it possible to mix Annotations and XML configuration for an Entity?

So, is possible to mix both configurations instead of use only one of those?

All I want is to keep all the configuration by Annotations and read the table by a XML.

Is it possible?

Thanks a lot.

Edit: How will be the hbm.xml file? I have this one:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="MyData" table="MyTable" >
    </class>
</hibernate-mapping>

And don´t compile the dtd.
