XSL transformation failed : Expected QName - xslt

Question

when I am trying to transform an XMl using below stylesheet, the transformation is failing with error Expected QName. What exactly is missing in the styelesheet, pasted below?
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dp="http://www.datapower.com/extensions" extension-element-prefixes="dp" exclude-result-prefixes="dp">
<xsl:output method="xml" indent="yes" version="1.0"/>
<xsl:variable name="origo-svc-augmented" select="'Y'"/>
<xsl:variable name="origo-svc-ns" select="'http://www.origoservices.com'"/>
<xsl:template match="node()">
<xsl:variable name="namespace" select="namespace-uri(.)"/>
<xsl:choose>
<!--xsl:when test="$namespace = ''
or ($origo-svc-augmented='Y' and $namespace=$origo-svc-ns)"-->
<xsl:when test="$origo-svc-augmented = 'N'">
<xsl:element name="{local-name()}">
<xsl:copy-of select="namespace::*[not(namespace-uri()=$origo-svc-ns)]"/>
<xsl:apply-templates select="#*|node()|comment()|processing-instruction()|text()"/>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:element name="{local-name()}" namespace="{$namespace}">
<xsl:copy-of select="namespace::*"/>
<xsl:apply-templates select="#*|node()|comment()|processing-instruction()|text()"/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
UPDATE: After applying the suggestion from the answer provided, the stylesheet is working fine, updated stylesheet is as below
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dp="http://www.datapower.com/extensions" extension-element-prefixes="dp" exclude-result-prefixes="dp">
<xsl:output method="xml" indent="yes" version="1.0"/>
<xsl:variable name="origo-svc-augmented" select="'Y'"/>
<xsl:variable name="origo-svc-ns" select="'http://www.origoservices.com'"/>
<xsl:template match="*">
<xsl:variable name="namespace" select="namespace-uri(.)"/>
<xsl:choose>
<!--xsl:when test="$namespace = ''
or ($origo-svc-augmented='Y' and $namespace=$origo-svc-ns)"-->
<xsl:when test="$origo-svc-augmented = 'Y'">
<xsl:element name="{local-name()}">
<xsl:copy-of select="namespace::*[not(namespace-uri()=$origo-svc-ns)]"/>
<xsl:apply-templates select="#*|node()|comment()|processing-instruction()|text()"/>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:element name="{local-name()}" namespace="{$namespace}">
<xsl:copy-of select="namespace::*"/>
<xsl:apply-templates select="#*|node()|comment()|processing-instruction()|text()"/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="#*|comment()|processing-instruction()|text()">
<xsl:copy>
<xsl:apply-templates select="#*|node()|comment()|processing-instruction()|text()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

I haven't tried it, but I think it may be because you're matching on node() (i.e. element, text node, processing instruction comment), but then trying to create an element with the name of that possibly non-element node. QName refers to a valid XML name, and I presume a text node, for example, wouldn't have one (when you call local-name()). You could change your template match to be *, and add another template for the other types.
