[xep-support] modify the origin coordinates

I create PDF files out of XSL-FOdata (generated out of an XSL file) with
XEP. Some of the PDF files need to have a "Bleed addition" (I don't know the
exact term in english).

Thus in the XSL we set two processing instructions:
<xsl:processing-instruction name="xep-pdf-crop-offset"><xsl:value-of
<xsl:processing-instruction name="xep-pdf-bleed"><xsl:value-of

The value of Page.Overflow is set to 5mm.

The company that is printing the PDFs is complaining about that the origin
coordinates seem to be set wrong in those PDFs resulting in the whole
document being shifted vertically when it is printed. They can manually
adjust this, but the whole production process is usually standarized because
they handle hundreds or thousands of PDFs each day.

In the resulting PDF, the boxes are defined as follows:
/MediaBox [-14.173 -14.173 991.587 637.795]
/CropBox [-14.173 -14.173 991.587 637.795]
/BleedBox [-14.173 -14.173 991.587 637.795]
/TrimBox [0 0 977.414 623.622]

Does anybody know whether the processing instructions are wrong, or what
else can cause such a behaviour? Can I find the origin coordinates in the
PDF (PDF-1.4) in some human readable form?

Any help would be greatly appreciated.

Best regards,

Christian Kirchhoff
