Have two parameters:

<xsl:param name="maxItemsFirstPage" select="50" />
<xsl:param name="maxItemsOtherPages" select="60" />

and choose which of those values to use according to which page you're
generating. I forget whether you're generating the pages all at once
or different ones with each process, but if the latter you could use a
global variable, for example:

<xsl:param name="current-page" select="3" />

<xsl:variable name="maxItemsPage">
  <xsl:choose>
    <xsl:when test="$current-page = 1">
      <xsl:value-of select="$maxItemsFirstPage" />
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="$maxItemsOtherPages" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>

I hope that helps,

Jeni
