overlay

An overlay is used to describe extra UI elements in the Xopus user interface.

<x:config xmlns:x="http://www.xopus.com/xmlns/config" version="1.0">
  <x:overlay xmlns="http://xopus.com/2009/lui">
    <toolbar-button/>
    <toolbar-button/>
  </x:overlay>
</x:config>

The Xopus for DITA setup from the Xopus distribution has an example of an overlay.

Note that the child elements of the overlay element use a different namespace from the configuration directives.

To position the new UI elements, or to hide existing ones, you can reference items by their ID. Here is the list of IDs of components in the toolbar:
