Orbeon Form Builder Toolbox
In Orbeon each application can have a library. This is implemented by creating a form in each application with the name "library" and each section of the form it is available in the toolbox to be used again and again.
Here is detailed how Orbeon build the global toolbox and the application toolbox. If a form named "library" is created in the application named "orbeon" then this is used as a global section library. If the name of the application is different to "orbeon" then the library is only available for that application.
