[xsl] generating a url to another drive on the local host

["Mark Wilson" <mark@xxxxxxxxxxxx>]

In XSLT, I am trying to output to an HTML file the URL
"file:///X:/2000-2009/2008/2008_05_SepOct.pdf"
but the style sheet always inserts the current directory in front of my 
construction:

"file:///C:/htm/X:/2000-2009/2008/2008_05_SepOct.pdf"

<a class="ref" href="{concat($journal-link, '/2000-2009/',$year, '/', 
$year, '_0', $issue, '_', $name)}" target="_blank"> Sep/Oct 2008 p30</a>

where:
$journal-link = file:X:
$year = 2008
$issue = 2008
$name = SepOct

What should the data in the XSLT construction look like to get rid of the 
insertion of the current directory?
Thanks,
Mark
