Inserting Acrobat PDF "comments" into a Docbook PDF

["Jeff Hooker" <Jeff_Hooker@pmc-sierra.com>]

Hi all,

Google and the Adobe PDF specification have let me down; let's see if
anyone here has the answer.

I'd like to be able to insert Acobat "comment" markers into the PDFs
that I generate using the DocbookXSL stylesheets so that reviewers can
simply use the "view next comment" feature in Acrobat rather than
scrolling through long documents looking for visual change markers (we
use DeltaXML to generate and style change markers). I can't find any
information on how to form the markers, etc. Has anyone else ever done
this? Got any ideas?

Thanks,
Jeff.
