I see that some subsystems use CHILDREN as the model key to describe the
subsystem root children, while others are using ATTRIBUTES. It does not
appear to make a different right now, but I assume it will at some point?
Logging:
subsystem.get(CHILDREN, CommonAttributes.ROOT_LOGGER,
DESCRIPTION).set(bundle.getString("root.logger"));
Transactions:
subsystem.get(ATTRIBUTES, CORE_ENVIRONMENT,
DESCRIPTION).set(bundle.getString("core-environment"));
