[xsl] schema reference in output

["Arjen F. de Vries (Gmail)" <afdevries@xxxxxxxxx>]

Dear Listees,

Im trying to transform XML to XML. In this transformation in trying to
extend the output by inserting a schema reference.

I'm using the SAXONb9-1-0-6n processor and Altova processor to test
the XSLT processing. Both give me the following error:

Error at xsl:attribute on line 23 column 19 of 400_o_pew_company.xslt:
  XTDE0850: Invalid attribute name: {xmlns:xsi}
Error at xsl:attribute on line 24 column 19 of 400_o_pew_company.xslt:
  XTSE0280: Undeclared namespace prefix {xsi}
Failed to compile stylesheet. 2 errors detected.

I have found the following site but Im not sure how to implement the
template option :

Thanks for your time!

The source XML file looks like :

<?xml version = "1.0" encoding="UTF-8"?>
<main datecreated="2009-04-17T17:00:02"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="400_o_emp_company.xsd">
<DATA_RECORD>
  <EMPLOYEENUMBER>012345</EMPLOYEENUMBER>
  <LASTNAME>Small</LASTNAME>
  <INITIALS>T</INITIALS>
  <FIRSTNAME>Toby</FIRSTNAME>
  <GENDER>M</GENDER>
  <DATEOFBIRTH>1960-04-22</DATEOFBIRTH>
 </DATA_RECORD>
 <DATA_RECORD>
  <EMPLOYEENUMBER>012346</EMPLOYEENUMBER>
  <LASTNAME>Bakker</LASTNAME>
  <INITIALS>H</INITIALS>
  <FIRSTNAME/>
  <GENDER>M</GENDER>
  <DATEOFBIRTH>1951-02-13</DATEOFBIRTH>
 </DATA_RECORD>
</main>

My transformation looks like :

</xsl:stylesheet>

XSD of the output file :
