Namespaces and XML

Hi,
I'm really confused now.  I have an xml document something like:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE lnv:COURTCASE PUBLIC "-//LEXIS Publishing//DTD COURT CASE STRICT
1.000//EN" "COURTCASE-V01.dtd">
<lnv:COURTCASE  cdi="11E200006B6700010008"
lni="3WY3-VH40-0039-403H-00000-00" src="11E2" > 
</lnv:COURTCASE>

The lnv: is all defined in the DTD which I have nothing to do with and can't
really change anyways.  But how do I get XSL to work with it.  

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:lnv="COURTCASE-V01.dtd" version="1.0">
<xsl:output method="text"/>
<xsl:template match="/">
{
<xsl:call-template name="lnv:COURTCASE"/>
<!--  <xsl:apply-templates/>  -->
}
</xsl:template>

<xsl:template match="lnv:COURTCASE">
Mmmbop
</xsl:template>

</xsl:stylesheet>

If I try this XSL, which works if I strip off all the namespaces in the XSL
and XML and just make everything COURTCASE instead of lnv:COURTCASE, I get
two possible errors, or at least results that I don't want.  If I use the
template-match, it never finds the lnv:COURTCASE template.  If I use
call-template, I get "XSL Error: Could not find template named:
COURTCASE-V01.dtd:COURTCASE".

Am I missing something really basic here?

Thanks,
Kerry.
