[xsl] Losing schemalocation

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

Hello,

I have the following decleration:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:sd="http://www.mygov.gov/schemas/ns/sdetail/2001/1.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.mygov.az.gov/schemas/ns/sdetail/2001/1.0
http://www.mygov.gov/schemas/sdetail/SDTransactions.xsd";
xmlns:date="http://exslt.org/dates-and-times"; exclude-result-prefixes="date">

Upon transformation, I am losing the following:

xmlns:xsl=...
xsl:schemaLocation=...

What is missing in my identity transformation?

Karl
