Saxon8: XML to XML transformation

I've got a little problem and don't know how to solve it. I use Saxon8
inside a JavaBean and want to transform some data from an XML file to
another XML file. If I use XMLSpy and apply the XSLT transformation to
the XML file I get the desired output, but not with Saxon8.

What am I supposed to do to get the same output like with XMLSpy? Why
does Saxon behave like that?

Thank you in advance,
with kind regards,
Marco

XML input:
---------------

<?xml version="1.0" encoding="UTF-8"?>
<molecule>
 <object>
   <variable name="marco"/>
 </object>
 <superclass isaType=":">
   <class>
     <constant name="employee"/>
   </class>
 </superclass>
</molecule>

XMLSpy output:
-----------------------
<?xml version="1.0" encoding="UTF-8"?>
<ObjectClassificationAtom class="employee">
       <ObjectVariable name="marco" class="employee"/>
</ObjectClassificationAtom>

Saxon8 output:
----------------------

<?xml version="1.0" encoding="UTF-8"?>
<ObjectClassificationAtom class="
     employee
   ">
 <ObjectVariable name="
   marco
 " class="
     employee
   "/>

my simple XSLT transformation:
----------------------------------------------
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:fn="http://www.w3.org/2006/xpath-functions"
xmlns:saxon="http://icl.com/saxon">
 <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

 <xsl:template match="/" >
   <xsl:apply-templates/>
 </xsl:template>

 <xsl:template match="molecule">
   <xsl:if test="superclass/@isaType = ':'">
     <xsl:element name="ObjectClassificationAtom">
       <xsl:attribute name="class">
         <xsl:apply-templates select="superclass/class/child::node()"/>
       </xsl:attribute>
       <xsl:apply-templates/>
     </xsl:element>
   </xsl:if>
 </xsl:template>

 <xsl:template match="object">
   <xsl:element name="ObjectVariable">
     <xsl:attribute name="name"><xsl:apply-templates/></xsl:attribute>
     <xsl:if test="../superclass">
       <xsl:attribute name="class">
         <xsl:apply-templates select="../superclass/class/child::node()"/>
       </xsl:attribute>
     </xsl:if>
   </xsl:element>
 </xsl:template>

 <xsl:template match="constant | variable | class">
   <xsl:value-of select="@name"/>
 </xsl:template>
 <!-- ignore all the rest -->
 <xsl:template match="*"/>
</xsl:stylesheet>
