pdf editor to simply insert notes?

[Robert P. J. Day]

  a colleague has a sizable book whose source is in docbook format,
and i want to mark it up with notes all over the place.  with an odt
or doc file, i would of course just open it in oowriter and insert
notes at will.

  with docbook, though, he's going to send me the PDF format of the
book, but i still don't know of a tool that will let me insert notes.
i have no need for general editing, just notes.  thoughts?
