Avalon items can contain many files, or sections as we call them. Each file can have only one XML document or "XML Item". Each "XML item" for which structure should be added should contain at least 1 Span with time codes in place.

In the Graphical editor, Part 2 is a Div with another Div and Span inside. The inside Div also contains Spans.
