Xslt: mapping different elements onto instances of an unbounded element

Question

How can you map different elements onto sequential elements of an unbounded type? For example:
<record>
<tag1>abc</tag1>
<tag2>def</tag2>
<tag3>ghi</tag3>
</record>
onto
<properties>
<property name="tag1" seq="1">abc</property>
<property name="tag2" seq="2">def</property>
<property name="tag3" seq="3">ghi</property>
</properties>
The mapping onto the first property will always be from tag1, etc. However, in the schema for <properties>, <property> only appears once:
<xsd:element name="property" type="NormalizedString" minOccurs="0" maxOccurs="unbounded">
Can this be mapped using JDeveloper? Can it be mapped by hand?
If so, how?
Thanks!

Hello user,
I think you will have to do this manually. It's been way too long since I was doing any serious XSLT hacking, and I don't have your schemas, but this may give you a starting point for your transformation;
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xref="http://www.oracle.com/XSL/Transform/java/oracle.tip.xref.xpath.XRefXPathFunctions"

xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"

<xsl:template match="/ns1:TransformationProcessRequest/ns1:record">
<xsl:for-each select="*">
<xsl:element name="ns1:property">
<xsl:attribute name="name"><xsl:value-of select="name()"/></xsl:attribute>
<xsl:attribute name="seq"><xsl:value-of select="position()"/></xsl:attribute>
<xsl:value-of select="current()"/>
</xsl:element>
</xsl:for-each>
</xsl:template>
<xsl:template match="/ns1:TransformationProcessRequest">
<ns1:properties>
<xsl:apply-templates select="/ns1:TransformationProcessRequest/ns1:record"/>
</ns1:properties>
</xsl:template>
<xsl:template match="/">
<ns1:TransformationProcessResponse>
<xsl:apply-templates select="/ns1:TransformationProcessRequest"/>
</ns1:TransformationProcessResponse>
</xsl:template>
</xsl:stylesheet>
Regarding validation to XSD, I guess that's just a matter of specifying the right namespaces and elements...?
