The documentation for the Infinispan Subsystem in Wildfly 10 (https://docs.jboss.org/author/display/WFLY10/Infinispan+Subsystem) suggest that it should be possible to set the following attributes on the transport element of the cache-container:

site: This attribute configures the site id of the cache container.
rack: This attribute configures the rack id of the cache container.
machine: This attribute configures the machine id of the cache container

Setting these will fail due to parsing errors:

[Host Controller] 14:32:41,557 ERROR [org.jboss.as.host.controller] (Controller Boot Thread) WFLYHC0033: Caught exception during boot: org.jboss.as.controller.persistence.ConfigurationPersistenceException: WFLYCTL0085: Failed to parse configuration
[Host Controller] Message: WFLYCTL0197: Unexpected attribute 'machine' encountered

Further investigation revealed that this failure was due to the configuration having been moved to the transport element of the jgroups subsystem. Therefore it would be good if this was removed from the documentation for the infinispan subsystem. However, if these settings affect the server hinting for infinispan (http://infinispan.org/docs/stable/user_guide/user_guide.html#ServerHinting) then some hint regarding these settings and how they pertain to server hinting would still need to be documented.
