    Make sure that the xmlns ID is added, even when the root node already
    exists, for instance when opening existing documents.

    * examples/example_lesson_planner.glom:
    * examples/example_music_collection.glom:
    * examples/example_project_manager.glom:
    * examples/example_smallbusiness.glom:
    * examples/sqlite/test_sqlite_music/test_sqlite_music.glom:
    Add the xmnls ID, to help to identify the MIME type of these documents.
