Mike W -- surprised by your note about the crop marks, I looked in the Help file and found, under Exporting PDF files > Commercial printing (PDF/X, 300 DPI images)... "Crop and printer's marks are included if these are switched on in the Print Options dialog in Xara Designer Pro X10." Any help? Not sure what I'm talking about here, since I haven't done any spot color work for years now. Am just assuming that DPX would burp out a set of PDFs, one for each color, all with your reg marks, if they were on the artboard?
