java – JBoss 7.1. 1 failed to start because of unexpected element ‘pool’

When I add a pool element, I receive the following error message:

If I delete a pool element, how it works I have checked the XSD in the docs folder. Am I sure this is right? Why did it fail?

<subsystem xmlns="urn:jboss:domain:resource-adapters:1.0">
        <resource-adapters>
            <resource-adapter>
                <archive>
