Recognition of the level of nesting for nested lists

[V0rlov]

Documents often contain nested lists and the nesting bears some meaning - see the TOC for the Docling Usage page for example:

Table of contents

• Conversion
  -- Convert a single document
  -- CLI
  -- Advanced options
  --- Adjust pipeline features
  ---- Control PDF table extraction options
  ---- Provide specific artifacts path
  --- Impose limits on the document size
  --- Convert from binary PDF streams
  --- Limit resource usage
• Chunking

At the moment, all of these items would be recognised as a single group with the same level 2 depth.

For a well formatted document, would be great to recognise the actual levels of nesting, which is easy for DOCX (as it is encoded in styles) and a bit less easy for PDF, where visual alignment is sometimes the only indicator.

Appreciate your thoughts on this - many thanks
