Running this with Saxon:
java com.saxonica.Transform -val schema-aware.xml schema-aware.xsl
First attempt gives the error message
Error at xsl:import-schema on line 9 of file:/c:/temp/schema-aware.xsl:
Schema at location schema-aware.xsd has target namespace
"http://www.fgeogres.org/dummy"
but requested namespace was ""
I corrected that by adding a namespace attribute to the import-schema
declaration. The output is now:
A 'list_type' element: 'list'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'
which is presumably what you expected.
The XSLT spec actually specifies what it means to omit the namespace
attribute rather indirectly, by reference to the semantics of xs:import in
the schema specification. The schema spec makes it clear that an absent
namespace attribute is a reference to a "no-namespace" schema. By
implication, XSLT inherits the rule for xs:import (in schema part 2 section
4.2.3):
The appropriate case among the following must be true:
3.1 If there is a namespace attribute, then its ·actual value· must be
identical to the ·actual value· of the targetNamespace attribute of [the
imported schema].
3.2 If there is no namespace attribute, then [the imported schema] must have
no targetNamespace attribute
I can't account for Altova's behavior - you'll have to ask them.

Subject: [xsl] [XSLT-2.0] Template rules matching elements by type
Hi
I'm trying the schema features of XSLT 2.0 and XPath 2.0,
with Altova XML (the only free schema-aware XSLT 2.0
processor I know). But I don't succeed for now to write a
template rule matching elements by type. Here is a minimal
example:
~> cat schema-aware.xsd
<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:my="http://www.fgeogres.org/dummy"
targetNamespace="http://www.fgeogres.org/dummy"
elementFormDefault="unqualified"
attributeFormDefault="unqualified">
<xs:complexType name="list_type">
<xs:sequence>
<xs:element ref="my:elem" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:simpleType name="elem_type">
<xs:restriction base="xs:string">
<xs:enumeration value="val1"/>
<xs:enumeration value="val2"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="list" type="my:list_type"/>
<xs:element name="elem" type="my:elem_type"/>
</xs:schema>
~> cat schema-aware.xsl
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:my="http://www.fgeogres.org/dummy">
<xsl:output method="text"/>
<xsl:import-schema schema-location="schema-aware.xsd"/>
<xsl:template match="node()">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="element(*,my:list_type)">
<xsl:text>A 'list_type' element: '</xsl:text>
<xsl:value-of select="name()"/>
<xsl:text>' </xsl:text>
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="element(*,my:elem_type)">
<xsl:text>An 'elem_type' element: '</xsl:text>
<xsl:value-of select="name()"/>
<xsl:text>' </xsl:text>
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
~> cat schema-aware.xml
<list xmlns="http://www.fgeogres.org/dummy">
<elem>val1</elem>
<elem>val2</elem>
<elem>val2</elem>
<elem>val1</elem>
</list>
~> altova-xml /xslt2 schema-aware.xsl /in schema-aware.xml
Not really what I did excpect.
Thanks,
