Oxygen XML Author Component
The Oxygen XML Author Component was designed as a subset of Oxygen XML Editor that can be integrated into another application under the terms of the Oxygen XML Editor SDK agreement to provide functionality for editing and authoring XML documents. The component can be embedded in a third-party standalone Java application to provide WYSIWYG-like XML editing directly in your application.
More information about the setup for the Oxygen XML Author Component can be found on the Oxygen SDK page.
