Xinclude prob

Hi!

I trying to use xinclude to merge another xml file with another one. 
I receiving this kind of message from the Xalan:

XSLT warning: Could not resolve prefix xi:include
(/var/www/xslt/BackToNormal.xsl, line 27, column 33)    

The src code of xsl file:

<date><xsl:text>Date: </xsl:text>
    <xi:include href="date.xml" parse="xml"/>
</Date>

This is what the result xml file looks like:
<Information xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xinclude="http://www.w3.org/1999/XML/xinclude"
xmlns:xi="http://www.w3.org/2001/XInclude">
<Border>
<LocateDate>
<TopicBorder>Location and Date</TopicBorder>
<Location>Location: </Location>
<Date>Date:
<xi:include href="date.xml" parse="xml"/>
</Date>

So the problem is that the file is not shown or "written" open 
to be visual. Hope ya understand what I meen =)
Please give me a helping hand.....
