What are the namespaces for persistence.xml in Jakarta EE 10?

General
1

In the section 8.3 of the specicification of Jakarta EE 10, it is written:

<persistence xmlns="https://jakarta.ee/xml/ns/persistence"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence
          https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd"
        version="3.0">
          ...
      </persistence>

However, the version of JPA for Jakarta EE 10 is 3.1, not 3.0. Is there a mistake in the specification?
The URL https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd is valid but the URL https://jakarta.ee/xml/ns/persistence/persistence_3_1.xsd generates a 404 error. So, I don’t know what to think.
Can someone help me?
