How to specify entity mappings in JPA 2.1?

A correct starting tag for the entity mappings file for JPA 2.0 was

<entity-mappings version="1.0" xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
    http://java.sun.com/xml/ns/persistence/orm_1_0.xsd">

What are the required corrections for JPA 2.1?

I tried 

<entity-mappings version="2.1" xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/orm">

But this gives the error:

No grammar constraints (DTD or XML Schema) referenced in the document.

According to official documentation, section 12.3 XML Schema:

<entity-mappings xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm
      http://xmlns.jcp.org/xml/ns/persistence/orm_2_1.xsd"
    version="2.1">
      ...
</entity-mappings>

For version 2.1 the following is working:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence version="2.1"
 xmlns="http://xmlns.jcp.org/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
  http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

As per what the JPA 2.1 spec says perhaps ;-) or the docs of a JPA 2.1 implementation that tells you

Change java.sun.com to xmlns.jcp.org

Change orm_1_0 to orm_2_1

Change version="1.0" to version="2.1"
