Try this one... added a few functions to ease the pain:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"

    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:function name="custom:equalPredecingItemCount" as="xs:integer">
      <xsl:param name="preceding_items"/>
      <xsl:param name="this_item"/>
      <xsl:value-of select="sum(for $item in $preceding_items return
custom:getEqualityValue($item, $this_item))"/>

    <xsl:function name="custom:getEqualityValue" as="xs:integer">
      <xsl:param name="item1"/>
      <xsl:param name="item2"/>
      <xsl:value-of select="if (deep-equal($item1, $item2)) then 1 else 0"/>

    <xsl:template match="node()|@*">
        <xsl:apply-templates select="node()|@*"/>

    <!-- we skip the item if it has at least 1 equal preceding item  -->
match="item1[custom:equalPredecingItemCount(preceding::item1, .) > 0]"/>

I find that I get the desired output, except for the last item1, which
is also removed, but that has a matching predecessor, i.e., the second
item1 in the output.
