That's my intention to do it in my zwpagelayout package. I often get
responses that my files are usable but lack some PDF/X data. I know
that there are packages that can do it but they depend on hyperref.
Unfortunatelly, hyperref is very huge and conflicts with other
packages (at least some versions), e.g. with Velthuis Devanagari (I
have not tried the latest version, maybe it was fixed). I want a
simple solution. Anyway, a file that should be used for printing and
never for use as a hypertext document does not need hyperref. I also
want to have my files verified on a real phototypesetter so it will
take some time to find the solution and I will have to reread the
specification. If someone has macros to share with me I would
certainly appreciate it.
