I like it!

interesting. I know we can call it what we like, but morally I'd
expect to consult the W3C about that

I cannot see any reason why this should not work. except that for
neatness I'd enclose all the toplevel fox:bookmarks in their own
wrapper element <fox:pdfextensions>. Because if we go down this line there
are plenty of other PDF-specific things one could get in here; these include

 - setting default view and startup mode
 - removing menu bar
 - page transition style
 - pdf title, subject, creator etc

seriously, if you want to produce `real world' PDF files, these are all
pretty important.

I think, trying to read Kelly's mind, that she was trying to do two
things at the same time, viz make bookmarks, and also put some clues
into the FO about the structure from which it was derived. The aim is
laudable, and I can imagine that one might *also* want to support some
derived PDF outlines as she proposed.

the real problem, for some people, with this proposal is that it
requires the FO generator to make another pass over the source. But I
for one will happily adopt it if others agree.
