This should work ok in your tl6 version. I'll send you the file off list.

Concerning steps, there are better ways. I'll try to send you the preview 
of show-pre.pdf [i'm on slow connections now, since our server is off line, 
due to sniffer/attack problems at the host]

In the current beta, there is a problem with cross doc refs [i adapted this 
to acrobat 5 and made an offset error]; this should be in spec-fdf.tex if 
you want optimize safe pdf files [awaiting a new pdftex feature -)]
