A side-note cannot be created in a note.
Hint
Only one side-note can be created per document. When you want
to create a side-note to replace the existing side-note, after
displaying the existing side-note in side-by-side format with the
document, tap (option) — [Create a New Side-Note for This
Document]. The old side-note will become a standalone note.
Side-notes are created as PDF files and can be handled the same
way as documents. After creation, the relationship between the
document and the side-note will be retained, even if the Digital
Paper App is used to move the document or the side-note to
another folder or to change the file name of the side-note.
