The `/Count' field specifies the number of sub-bookmarks.  A negative
number indicates that the bookmark is closed; no `/Count' means there
are no sub-bookmarks.  Thus, it has nothing to do with the depth level.

Integrating it into the definition of address@hidden' (or
whatever it's named) would require fetching the number of
sub-structures, which I suspect is uneasy.

Good luck!

Ludovic.
