This will require the xxx:node-set() extension function, won't it?

And probably copying of all xml documents into a temporary tree can be
avoided?

Here's one way:

Using FXSL, the following transformation:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:mytestElem="f:mytestElem"
>
    <xsl:import href="foldl.xsl"/>

    <xsl:output indent="yes" omit-xml-declaration="yes"/>
    <mytestElem:mytestElem/>
    <xsl:template match="/">
      <xsl:variable name="vFun-testElem"
                    select="document('')/*/mytestElem:*[1]"/>

      <xsl:call-template name="foldl">
        <xsl:with-param name="pFunc" select="$vFun-testElem"/>
        <xsl:with-param name="pA0" select="/.."/>
        <xsl:with-param name="pList"
                   select="document('testDistinct11.xml')/itemList/item
                         | document('testDistinct22.xml')/itemList/item
                         |
document('testDistinct33.xml')/itemList/item"
        />
      </xsl:call-template>
    </xsl:template>

    <xsl:template match="mytestElem:*">
      <xsl:param name="arg1" select="/.."/>
      <xsl:param name="arg2" select="/.."/>

      <xsl:copy-of select="$arg1"/>
      <xsl:if test="not($arg2/@name = $arg1/@name)">
        <xsl:copy-of select="$arg2"/>
      </xsl:if>
    </xsl:template>
</xsl:stylesheet>

when applied to a dummy source xml:
</t>

and when the referenced documents 'testDistinct11.xml',
'testDistinct22.xml', 'testDistinct33.xml' have the contents provided
in
the original message, then the result is:

<item name="one">value_1</item>
<item name="two">value_2</item>
<item name="three">value_3</item>
<item name="seven">value_7</item>
