In XSLT 2.0 you can use:

    <xsl:for-each-group select="/dsWMSRpt/WMSReport"
group-by="ReportUnitTitle">
        Administration Code: <xsl:value-of select="AdministrationCode"/>
        Report Title:        <xsl:value-of select="ReportUnitTitle"/>
        <xsl:for-each select="current-group()/PositionNumber">
             Position Number:      <xsl:value-of select="."/>
        </xsl:for-each>
    </xsl:for-each-group>

You will have to sort out the whitespace issues, but you get the idea.
It's worth noting that your output doesn't match your input, because
"Financial Div/Headquarters" and "Financial Div" are different, as are
"Human Resource Div" and "HumanResource Div" when you've grouped using
them.
