Accessing 2 xml files in xsl

I have 2 xml files out of which one is linked to a xsl file.The xsl file
produces html output but it has to access both the xml files.Can anyone tell
me how I can do that?.I remember David saying about xsl:apply-templates
match=document("test.xml") sometime back but can someone give me an example
pl?.

 This is just a rough sketch

xml1

<?xml-stylesheet type="text/xsl" href="layout.xsl"?>
<bwlabels>
	<header>... </header>
	 <address1>... </address1>
	 <address2>... </address2>
	 <address3>... </address3>
</bwlabels>


xml2

<layout>
	<alertmsg>You must enter three or more characters to perform a
search.</alertmsg>
	<pr>Projects</pr>
	 
	<productdetails>
		<type>Product Search</type>
		<pcontent1>Item Number</pcontent1>
		<pcontent2>Name</pcontent2>
		<pcontent3>Quick Guides</pcontent3>
		<pcontent4>Password</pcontent4>
		<pcontent5>New Items</pcontent5>
		<pcontent6>Work Area</pcontent6>
		<pcontent7>Reports</pcontent7>
		<pcontent8>Logoff</pcontent8>
	</productdetails>
</layout>


I need to use both these xml files in my layout.xsl.
