We don't especially support the production of PDF/X1 (or PDF/X2) files, so 
there is no quick way to do this.

However you could probably do it yourself; start by setting the PDFX switch 
and then customise the 'defs' file. Normally for a PDF/X-3 file you would 
use the file, if you changed the line:

[ /GTS_PDFXVersion (PDF/X-3:2002) % Must be so (the standard requires).


[ /GTS_PDFXVersion (PDF/X-1:2001) % Must be so (the standard requires).

The file will be identified as a PDF/X1 file. You might also have to add a 
line like:

/GTS_PDFXConformance (PDF/X-1a:2001)

to make it specifically X1-a conformant.

Other than that its just a matter of setting the various pdfwrite controls 
so that the PDF file is produced in a manner conforming to the PDF/X1-a 
specification. I don't happen to have a copy of the spec, but the from the 
application note it looks like it should be possible.
