XmlException "Root element is missing" on XslCompiledTransform.Load method

When I try to load my xslt i get an xml exception with the message "Root
element is missing". The stylesheet works when I preview it in stylus
studio, but apparently not in my application. Any ideas what may be wrong?

The stylesheet:

<?xml version="1.0" encoding="utf-8"?>
<xsl:transfor m version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" >
<xsl:output indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="PC"/>
</xsl:template>

<xsl:template match="PC">
<xsl:element name="pcf:PC" namespace="http ://www.protang.se/ProFrame">
<xsl:attribut e name="name">
<xsl:value-of select="@name"/>
</xsl:attribute>
<xsl:apply-templates select="type"/>
<xsl:apply-templates select="*/@name"/>
</xsl:element>
</xsl:template>

<xsl:template match="type">
<xsl:copy>
<xsl:copy-of select="node()"/>
</xsl:copy>
</xsl:template>

<xsl:template match="@name">
<xsl:element name="{.}">
<xsl:attribut e name="name">
<xsl:value-of select="local-name(..)"/>
</xsl:attribute>
<xsl:if test="current() ='option'">
<xsl:attribut e name="present">
<xsl:value-of select="../@present"/>
</xsl:attribute>
</xsl:if>
<xsl:copy-of select="../node()"/>
</xsl:element>
</xsl:template>

</xsl:transform>
