You are absolutely right on both counts---but layout systems take care 
of the printing process too, in a sense. LaTeX/TeX is similar to 
InDesign/Quark in this respect. They can all produce crop marks at 
will. You are nonetheless right that crop marks are outside the page, 
logically speaking. It's probably a good decision to leave them  out of 
XeTeX, as long as other solutions are available.

I noticed. and I hope it will have a long and satisfying life. The 
management of fonts (in a broad sense, not just typefaces, but glyphs, 
sccripts, etc)  seems to me to be the most important issue that LaTeX 
faces to become a very viable system outside of its traditional 
technical niche. (and too bad for non-Mac users...)

I might explore that option, thanks for the hint. Although I must say 
the prospect of rerunning a 300-odd pages manuscript twice trhough 
LaTeX (or XeTeX plus LaTeX) to produce final output makes me cringe. 
You keep referring to the crop-mark option in Apple's Print manager, 
BTW, but I could not find any such thing. Unfortunately I do not have 
access to Acrobat Pro to try that one out.

Cheers,

Stefano
