If 2.0 you can do:

<xsl:for-each select="1 to 3">
  <item>
    <type>type<xsl:value-of select="."/>
     ...


In 1.0 you really need a recursive template:

<xsl:call-template name="generate">
  <xsl:with-param name="count" select="3"/>
</

<xsl:template name="generate">
  <xsl:param name="count"/>
  <xsl:if test="$count > 0">
    <item>
      <type>type<xsl:value-of select="$count"/>
      </
    </
    <xsl:call-template name="generate">
      <xsl:with-param name="count" select="$count - 1"/>
    </
  </xsl:if>
</xsl:template>
