In table 6.1 at https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/8.0/html/using_jboss_eap_on_openshift_container_platform/assembly_provisioning-a-jboss-eap-server-using-the-maven-plugin_default#ref_configuration-items-offered-by-the-maven-plug-in_default, the channels descriptions mentions that:

If you deploy the channel YAML file artifact in a Maven repository with the channels classifier, then you can identify it using its Maven coordinates: groupId, artifactId and optional version. If version is not set, it uses the latest channel version

`version` is an actual configuration parameter and should be displayed in the same convention than groupId and artifactId. The paragraph should look like:

If you deploy the channel YAML file artifact in a Maven repository with the channels classifier, then you can identify it using its Maven coordinates: groupId, artifactId and optional version. If version is not set, it uses the latest channel version

The text could even be further clarified with:

If the channel YAML artifact is deployed in a Maven repository, then you can identify it using its Maven coordinates: groupId, artifactId and optional version. If version is not set, it uses the latest version that has been deployed.
