Hi Hans, thank you very much for looking into that!
I wikified the box information plus your example at 
http://wiki.contextgarden.net/PDF_Boxes

Unfortunately, the order (crop < trim < bleed < art) is not so good, it should 
be (art < crop < trim < bleed) - as I wrote, in PDF/X, ArtBox must be the same 
as TrimBox, if defined at all. Would you please fix this?

(I don’t know any use of ArtBox - it was meant for imposition, but software 
will probably look for page contents itself, since ArtBox is mostly undefined.)

Greetlings, Hraban
