The help element
Release 2.0 - ...
The author-optional element help provides a convenient way to attach help information to a form control.
The message specified can exist in instance data (using a Single Node Binding) or as inline text, where when both specified a Single Node Binding takes precedence over inline text.
A modeless message is the foundation for displaying a help message. The help message itself will never be rendered directly, it needs to be invoked by dispatching the xforms-help event to the control.
