Number of outline levels between a note and the document root (read-only).

Actually, it is 1 + the number as 'top-level' notes have $OutlineDepth of 1, notes inside a top-level container have$ OutlineDepth of 2, and so forth.

Aliases do not inherit this property from their original but have their own intrinsic value.
