XSD minOccurs="0" with transform

[IsValidUN]

If an xsd indicates that an element within a doc is minOccurs="0"
and you're using xsl to transform the doc do you have to do some kind of check prior to doing a transform on the element?

For instance if my output doc had an xsd element defined as
<xs:element name="CertificationDate" type="xs:dateTime" minOccurs="0"/>

and I had an input xml file like
<doc>
<node1> </node1>
<node1><certdate>2006-06-12T00:00:00.000-08:00</certdate> </node1>
</doc>

I want to output to be like:
<doc>
<node1> </node1>
<node1><CertificationDate>2006-06-12T00:00:00.000-08:00</CertificationDate> </node1>
</doc>


What would i need to do in XSL?

<xsl:for-each select="doc/node1">
<node1>
<CertificationDate><xsl:value-of select="cert_date"/></CertificationDate>
</node1>
</xs:for-each>

If you only want it to show when there is a cert_date element, use <xsl:apply-templates/> instead, and add a template for cert_date
<xsl:template match="cert_date">
<CertificationDate><xsl:value-of select="."/></CertificationDate>
</xsl:template>

Otherwise, you've pretty much answered your own question.
