xsd to text via xslt ?

I'm trying to extract text from an xsd file.

E.g. The XSD is:

<?xml version="1.0" standalone="yes"?>
<xs:schema id="Publications" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="Publications" msdata:IsDataSet="true" msdata:Locale="en-GB" msdata:EnforceConstraints="False">
<xs:complexType>
<xs:choice maxOccurs="unbounded">
<xs:element name="Publications">
<xs:complexType>
<xs:sequence>
<xs:element name="Publication_Name" type="xs:string" minOccurs="0" />
<xs:element name="Period" type="xs:string" minOccurs="0" />
<xs:element name="Offer" type="xs:string" minOccurs="0" />
<xs:element name="Suffix" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

Using xslt :

<?xml version="1.0" encoding="UTF-8" ?>
<stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform">
<output method='text' indent='yes' doctype-public='-//W3C//DTD HTML 3.2 Final//EN'/>

<template match='/'>
<value-of select='xs:schema/@id'/>
</template>
</stylesheet>

However when I run the transofrmation I get a "...prefix 'xs' is not defined...". however if I delete the xs: suffix I don't get the value of the variable. Has anyone got a solution?

Kind Regards, Ticom...
