Consider the following classes:

@XmlRootElement
@XmlSeeAlso({Dog.class, Cat.class})
public class Animal {
	public String name;
}

@XmlRootElement
public class Cat extends Animal {
	public int sleepTime;
	public Dog enemy;
}

public class Dog extends Animal {
	public String barkLevel;
}

Note that both Animal and Cat have @XmlRootElement defined.

When a new Cat is created and marshalled, an unnecessary xsi:type attribute is written out:

<?xml version="1.0" encoding="UTF-8"?>
<cat xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="cat">
   <name>Fluffy</name>
   <sleepTime>10</sleepTime>
   <enemy>
      <name>Buster</name>
      <barkLevel>LOUD</barkLevel>
   </enemy>
</cat>
