The components.e4xml can be opened with the "E4 WorkbenchModel Editor"
Visual Design Editor is a WYSIWYG editor. It can edit and visualize the entire e4 application. We have not investigated to edit in WYSIWYG way a component file. In the worst case, Visual Design Editor should enable to open the file without the WYSIWYG design capability. Outline view and properties view should work.
