This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:t="http://test.com"
>
     <xsl:output omit-xml-declaration="yes" indent="yes"/>
     <xsl:strip-space elements="*"/>

     <xsl:param name="pTimes" select="2"/>

     <xsl:template match="node()|@*">
      <xsl:param name="pPosition" select="1"/>
      <xsl:copy>
       <xsl:apply-templates select="node()|@*">
         <xsl:with-param name="pPosition" select="$pPosition"/>
       </xsl:apply-templates>
      </xsl:copy>
     </xsl:template>

     <xsl:template match="t:test">
         <xsl:call-template name="applyNTimes">
             <xsl:with-param name="pTimes" select="$pTimes"/>
             <xsl:with-param name="pPosition" select="1"/>
         </xsl:call-template>
     </xsl:template>

     <xsl:template name="applyNTimes">
         <xsl:param name="pTimes" select="0"/>
         <xsl:param name="pPosition" select="1"/>

         <xsl:if test="$pTimes > 0">
             <xsl:choose>
             <xsl:when test="$pTimes = 1">
                 <xsl:apply-templates select="*">
                 <xsl:with-param name="pPosition" select="$pPosition"/>
                 </xsl:apply-templates>
             </xsl:when>
             <xsl:otherwise>
                 <xsl:variable name="vHalf" select="floor($pTimes div 2)"/>

                 <xsl:call-template name="applyNTimes">
                 <xsl:with-param name="pTimes" select="$vHalf"/>
                 <xsl:with-param name="pPosition" select="$pPosition"/>
                 </xsl:call-template>

                 <xsl:call-template name="applyNTimes">
                 <xsl:with-param name="pTimes" select="$pTimes - $vHalf"/>
                 <xsl:with-param name="pPosition" select="$pPosition + $vHalf"/>
                 </xsl:call-template>
             </xsl:otherwise>
             </xsl:choose>
         </xsl:if>
     </xsl:template>

     <xsl:template match="t:Person">
         <xsl:param name="pPosition" select="1"/>

         <xsl:copy>
             <xsl:copy-of select="@*"/>
             <xsl:attribute name="position">
              <xsl:value-of select="$pPosition"/>
             </xsl:attribute>
             <xsl:apply-templates>
             <xsl:with-param name="pPosition" select="$pPosition"/>
             </xsl:apply-templates>
          </xsl:copy>
     </xsl:template>

     <xsl:template match="t:number">
          <xsl:param name="pPosition" select="1"/>
            <xsl:copy>
              <xsl:value-of select="$pPosition"/>
            </xsl:copy>
     </xsl:template>
</xsl:stylesheet>

when applied on the provided XML document:

<header xmlns="http://test.com" >
    <Batch>
        <test document="dump" >
            <Person position="1">
                <properties>
                    <name>John</name>
                    <number>1</number>
                </properties>
            </Person>
        </test>
    </Batch>
</header>

produces the wanted results:

<header xmlns="http://test.com">
    <Batch>
        <Person position="1">
            <properties>
                <name>John</name>
                <number>1</number>
            </properties>
        </Person>
        <Person position="2">
            <properties>
                <name>John</name>
                <number>2</number>
            </properties>
        </Person>
    </Batch>
</header>
