Basic validation question

Question

Hi,
So I wrote a simple schema, and am now trying to parse it with a validating parser. My code is:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
This complains several messages and I don't understand why -- it seems like it doesn't realize that it's being given an XSD file, and complains about the tags not being known and so forth.:
Error: URI=file:C:/cygwin/home/Administrator/transform/Program/ViewSDT/Preferences/Preferences.xsd Line=2: Element type "xsd:schema" is not declared.

My schema is:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<xsd:element name="drawingsetup" type="drawingsetupType"/>
<xsd:complexType name="drawingsetup">

<xsd:attribute name="version" type="xsd:string"/>
<xsd:attribute name="author" type="xsd:string"/>

<xsd:element name="hdist" type="xsd:integer"/>
<xsd:element name="vnamepad" type="xsd:integer"/>
<xsd:element name="hnamepad" type="xsd:integer"/>
<xsd:element name="fontsize" type="xsd:integer"/>
<xsd:element name="background" type="color"/>
<xsd:element name="line" type="color"/>
<xsd:element name="colorscheme" type="colorscheme" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="colorscheme">
<xsd:sequence>
<xsd:attribute name="name" type="xsd:string"/>
<xsd:element name="background" type="color"/>
<xsd:element name="border" type="color"/>
<xsd:element name="text" type="color"/>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="color">
<xsd:restriction base="xsd:string">
<xsd:pattern value="#\[0-9A-Fa-f]{6}"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
Any ideas on what I need to change? Thanks!
