how to check the tag exists and the value is 'On' do something in xsl

please correct me.,

<xsl:if test="$status and $status='On'">

 //do something

</xsl:if>

can we skip checking whether the tag exists and direclty check for the value.

<xsl:if test="$status='On'">

     //do something

    </xsl:if>

is it a correct practice.,
