single sided document

Hello,
I'd like to have single sided PDF document with left margin: 57mm an right
margin: 15mm

here is part of my XSL customization layer:

--------
<xsl:param name="double.sided" select="0" />

<xsl:param name="xep.extensions" select="1"/>
<xsl:param name="paper.type" select="'A4'"/>
<xsl:param name="page.margin.inner" select="'57mm'"/>
<xsl:param name="page.margin.outer" select="'15mm'"/>
--------

but PDF output have some pages with left margin 57mm and some pages have
mirrored margins. It looks like double sided output.

Where is the problem?




Thanks in advance.


Mike
