XSLT and namespaces in XML nodes

[Hexonx]

I'm transforming a document from one XML schema to another using MSXML 4.0. One of the elements in the stylesheet has a namespace reference in the element node. The value of this node is populated with <xsl:value-of >. When executing the transform, I get a parse error: &quot;value-of not allowed in this context&quot;.

Source document (investments.xml)
<?xml version=&quot;1.0&quot;?>
<investments>
<item type=&quot;stock&quot; exch=&quot;nyse&quot; symbol=&quot;ZCXM&quot; company=&quot;zacx corp&quot;
price=&quot;28.875&quot;/>
<item type=&quot;stock&quot; exch=&quot;nasdaq&quot; symbol=&quot;ZFFX&quot; company=&quot;zaffymat inc&quot;
price=&quot;92.250&quot;/>
<item type=&quot;stock&quot; exch=&quot;nasdaq&quot; symbol=&quot;ZYSZ&quot; company=&quot;zysmergy inc&quot;
price=&quot;20.313&quot;/>
</investments>

Stylesheet(portfolio.xsl)
<?xml version=&quot;1.0&quot;?>
<xsl:stylesheet xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;

version=&quot;1.0&quot;>
<xslutput method=&quot;xml&quot; indent=&quot;yes&quot;/>
<xsl:template match=&quot;/&quot;>
<portfolio xmlns:dt=&quot;urn:schemas-microsoft-com:datatypes&quot;>
<xsl:for-each select=&quot;investments/item[@type='stock']&quot;>
<stock>
<xsl:attribute name=&quot;exchange&quot;>
<xsl:value-of select=&quot;@exch&quot;/>
</xsl:attribute>
<name><xsl:value-of select=&quot;@company&quot;/></name>
<symbol><xsl:value-of select=&quot;@symbol&quot;/></symbol>
<price><xsl:value-of select=&quot;@price&quot;/></price>
<!--
This line is from the original MSXML 4.0 SDK docs,
but causes an error: &quot;value-of not allowed in this context&quot;.
Removing the namespace declaration resolves the problem.
<price dt:dt=&quot;number&quot;><xsl:value-of select=&quot;@price&quot;/></price>
-->
</stock>
</xsl:for-each>
</portfolio>
</xsl:template>
</xsl:stylesheet>

Why would the &quot;dt&quot; namespace have any effect on the transform? It's in the static text of the template!

BTW - This came from the MSXML 4.0 SDK docs. Search for 'Translating from One XML Schema to Another'.
