I'm starting reading;)
I see it's guite complicated. So I have the last question. How do you
create xetex documents that don't look like classic LaTeX document. I
mean modern-looking pdfs (created mainly in InDesign) with for example
headings in Helvetica in fancy colours. Of course with use of OpenType
fonts.
