How to I display currentindicator="true" for an element (approximateDateOfBirth)?

What I want to do is to change my xslt code so that when the xml document only one of ApproximateDate as in my xml document here below, then change the currentIndicator="false" to currentIndicator="true".

Desired Output

<ext:PersonBirthDate>
        <ext:PersonBirthDate approximateDateIndicator="true" currentIndicator="true">1956-03-04</ext:PersonBirthDate>
</ext:PersonBirthDate>

Current output

<ext:PersonBirthDate>
            <ext:PersonBirthDate approximateDateIndicator="true" currentIndicator="false">1956-03-04</ext:PersonBirthDate>
        </ext:PersonBirthDate>

Here is the xml document code

    <Party ID="6" InternalPartyID="27">
        <Gender Word="F ">Female</Gender>
        <ApproximateDOB>3/4/1956</ApproximateDOB>
    </Party>

**Here is my xslt code**

    <!--
New Code templates for the DateOfBirth and Approximate date for the respondent
-->
<xsl:template match="DateOfBirth">
    <ext:PersonBirthDate>
        <xsl:attribute name="approximateDateIndicator">false</xsl:attribute>
        <xsl:attribute name="currentIndicator">false</xsl:attribute>
        <xsl:value-of select="mscef:formatDate(string(.))"/>
    </ext:PersonBirthDate>
</xsl:template>

<xsl:template match="DateOfBirth[@Current='true']">
    <ext:PersonBirthDate>
        <xsl:attribute name="approximateDateIndicator">false</xsl:attribute>
        <xsl:attribute name="currentIndicator">true</xsl:attribute>
        <xsl:value-of select="mscef:formatDate(string(.))"/>
    </ext:PersonBirthDate>
</xsl:template>

<xsl:template match="ApproximateDOB">
    <ext:PersonBirthDate>
        <xsl:attribute name="approximateDateIndicator">true</xsl:attribute>
        <xsl:attribute name="currentIndicator">false</xsl:attribute>
        <xsl:value-of select="mscef:formatDate(string(.))"/>
    </ext:PersonBirthDate>
</xsl:template>

<!--Respondent Template-->
<xsl:template name="Respondent">
    <xsl:param name="pProtectionOrderID"/>
<ext:Respondent>
    <nc:PersonEyeColorCode>
        <xsl:value-of select="EyeColor/@Word"/>
    </nc:PersonEyeColorCode>

<!--Guardian -->
<xsl:for-each select="//CaseParty[(Connection[(@Word='GRD')])][1]">
    <xsl:for-each select="//Party[@InternalPartyID=current()/@InternalPartyID]">
        <xsl:call-template name="Guardian"/>
        <xsl:apply-templates select="ApproximateDOB|DateOfBirth"/>
    </xsl:for-each>
</xsl:for-each>

    <ext:PersonBirthDate>
        <xsl:apply-templates select="ApproximateDOB|DateOfBirth" />
    </ext:PersonBirthDate>
</ext:Respondent>
