[xsl] How to generate an xmlns attribute with a prefix

[Marc Van Limberghen <marc2jogger@xxxxxxxxx>]

Hello,
I am transforming with XSL a source XML to a target XML. I can design the source XML myself. I can not decide on the structure of the target XML.
The target XML must have as its root element the following piece of XML:
<beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"; default-lazy-init="true">

I could obtain the xmlns attribute in my target XML, by putting it in the <xsl:stylesheet> element.
But I do not find a way to generate either the xmlns:xsi and xsi:schemaLocation attributes.
I read a lot of FAQs on namespaces and prefixes but could not find an answer.

I use:
XML version 1.0
XSLT Stylesheet version 1.0
Xalan XSLT processor Xalan-Java v 2.7.1 (but I donot use Java, I use XSL)

All help is much appreciated!
Marc
