XML error

I have just finished writing a simple XML / XSL script and when I try to transform them using ASP, I get the following error:

Error Type:
msxml3.dll (0x80004005)
The stylesheet does not contain a document element. The stylesheet may be empty, or it may not be a well-formed XML document.
/includes/content.asp, line 13

XML:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="content.xsl"?>
<content>
<entity id="glass">
<description>TEST</description>
</entity>
</content>

XSL:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<xsl:for-each select="content/entity[@id='glass']">
<xsl:attribute name="STYLE">
font-family: Arial;
font-size: 11px;
font-weight: normal;
</xsl:attribute>
<table>
<tr>
<td><xsl:value-of select="description"/></td>
</tr>
</table>
</xsl:for-each>

</xsl:template>
</xsl:stylesheet>

Does anyone have any ideas what is causing this proble, if I run the XML file it displays without any problem.

reinstall the MSXML 3..0 SDK.
