We have a <help> section in plugins that is used e.g. in the Hibernate, Platform and JMX-Plugin. For Platform and JMX plugins, that help is shown in the UI Admin->Agent Plugins-><plugin details> For Hibernate that is not shown. Looking at the database shows that this help is missing in the help column for the Hibernate plugin, which indicates that the plugin parser is skipping this for whatever reason.
It turns out that this is a bug in the plugin descriptor, where the <help> element is not at top level (below <plugin>), so that it is not found on plugin level. The XSD allows for help on the level of platform/server/service, which explains why plugin validation did not catch that). This information is not used though.
