[xslt] bug? warning given as error

[S Woodside <sbwoodside yahoo com>]

This seems like a possible bug in Apache::AxKit::Provider::File. For a  
document() call on a non-existing file, xsltproc gives a warning, on  
the same test files AxKit gives an error.
Using libxml 20506, libxslt 10029 and libexslt 719
AxKit 1.6.1

I generated a simple testcase.

=========================
test.xml
=========================

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>
<foo>bar</foo>

=========================
test.xsl
=========================

<?xml version="1.0"?>
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   version="1.0">

   <xsl:output method = "html" />

   <xsl:template match="/">
     <xsl:value-of select="'foo'"/>
     <xsl:value-of select="document('test.xml')"/> <!-- *** -->
   </xsl:template>
</xsl:stylesheet>

=========================
Output in xsltproc & AxKit
=========================

foobar

=========================
Error condition
=========================

Change the line marked with *** to:
     <xsl:value-of select="document('test.xmlasdfa')"/> <!-- *** -->


=========================
Output in xsltproc
=========================

% xsltproc test.xml
warning: failed to load external entity "test.xmasdfl"
foo

=========================
Output in AxKit
=========================
