The author is proposing that the DAG representation be in addition to the PDF:

My opinion: Ideally the PDF could be generated from the underlying DAG -- that would give you confidence that everything in the PDF has been captured in the DAG.

You could generate the document from the graph and then attach it as data.

Much easier for doctors to draft PDFs than graphs.

I have not drafted a PDF myself and I doubt doctors will. They work in a text writer or spreadsheet application and then export or print to PDF would be my guess. An interactive interface could spit out the PDF with the decision three in the end. This solution would still mean the decision tree source is in some software package.
