This is more like a suggestion:

In the code snippet for infinispan the 5.2 versioned namespace is used, although the documentation is for JDG 6.2. So perhaps it worth to use the infinispan 6.0 namespace, so that the code looks like:

<?xml version="1.0" encoding="UTF-8"?>
<infinispan
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="urn:infinispan:config:6.0 http://www.infinispan.org/schemas/infinispan-config-6.0.xsd"
      xmlns="urn:infinispan:config:6.0">
   <default>
      <indexing enabled="true" indexLocalOnly="true">
         <properties>
            <property name="default.directory_provider" value="ram" />
         </properties>
      </indexing>
   </default>
</infinispan>
