BizTalk Map Name Value Pair to Hierarchical Schema - xslt

Question

I'm going to be working the MS AX2010. When accessing data through an AX WCF service, the response is XML containing name / value pairs - known as a key data list. I'll be collecting this XML in BizTalk and needing to transform it to a canonical hierarchical schema. So for example, if I read a source Name element with "OrderNumber", then I would map the associated Value to an OrderNumber element in the destination schema.
Has anyone discovered a nice way to do this using a BizTalk map?

I acknowledge that you prefer to use the graphical functoids, but if you can accept an xslt route, it is pretty straightforward (See here for converting a visual map to an xslt). eg. the following XSLT
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns0="inputxmlns"
xmlns:ns1="outputxmlns"
exclude-result-prefixes="ns0"
>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/ns0:Root">
<ns1:Root>
<ns1:Elements>
<xsl:for-each select="ns0:Elements/ns0:Element">
<xsl:element name="ns1:{normalize-space(*[local-name()='Name']/text())}">
<xsl:value-of select="ns0:Value/text()"/>
</xsl:element>
</xsl:for-each>
</ns1:Elements>
</ns1:Root>
</xsl:template>
</xsl:stylesheet>
Will transform a quasi EAV schema:
<?xml version="1.0" encoding="utf-8"?>
<Root xmlns="inputxmlns">
<Elements>
<Element>
<Name>
NameOfElement1
</Name>
<Value>
ValueOfElement1
</Value>
</Element>
<Element>
<Name>
NameOfElement2
</Name>
<Value>
ValueOfElement2
</Value>
</Element>
</Elements>
</Root>
To this:
<?xml version="1.0" encoding="utf-8"?>
<ns1:Root xmlns:ns1="outputxmlns">
<ns1:Elements>
<ns1:NameOfElement1>
ValueOfElement1
</ns1:NameOfElement1>
<ns1:NameOfElement2>
ValueOfElement2
</ns1:NameOfElement2>
</ns1:Elements>
</ns1:Root>
