It's actually pretty easy to do registration marks (and CMYK bars). I 
just created appropriate registration marks and color bars in 
Illustrator as EPS files and then I use one of the edge region with 
absolutely-positioned block containers to place the marks. I use normal 
block-containers with borders to create crop marks. It's actually pretty 
easy to create a registration mark graphic by hand just by typing up an 
EPS directly--it's also a good exercise for learning the Postscript 
drawing commands. Only requires about 15 lines of code to create a 
couple of circles with a cross or to create a circle filled with 
radiating lines.

It just requires using a large enough page size so you have room for the 
registration and crop marks outside the final trimmed page area. By 
using this technique you can also create bleeds since you have plenty of 
extra width in the edge regions.

But it would be handy to be able to set the bleedbox within the PDF.

Cheers,

Eliot
