WebSphere 8 persistence.xml syntax error (expected root element)

Question

Installing my web application to WebSphere Application Server 8 fails due to a syntax error in my persistence.xml. According to my IDE, there is no error. What is the actual problem?

persistence.xml:

  <?xml version="1.0" encoding="UTF-8"?>
  <persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                                  http://java.sun.com/xml/ns/persistence/persistence_2_1.xsd"
  >
      <persistence-unit name="myapp">
          <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
      </persistence-unit>
  </persistence>

Excerpts from stack trace (SystemOut.log):

1:

Caused by: com.ibm.ws.metadata.MetaDataException: CWWJP0040E: The persistence.xml in application PA_Appl, module Appl-0.1.war, has a syntax error at line number: 6, column number: 2.

2:

Caused by: org.xml.sax.SAXParseException: expected root element {http://java.sun.com/xml/ns/persistence}persistence

Try this

<?xml version="1.0" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
<persistence-unit name="myapp">

  </persistence>
