I just mean an algorithm that maps every node in the document to its 
header, or equivalently every header in the document to the list of nodes 
that are in its section, with a definition of how each such "section" 
relates to other sections in the document, structurally.

Which happens to be exactly what you need to know to create an outline, 
so in the interests of simplicity and clarity I figured it was easier to 
just ask for an algorithm for creating an outline.
