There may be several issues to get to what I am looking for.  I am trying to
apply a transform that contains a call to the document() function.

Test I wrote compiles and works on .Net 2.0.  It fails to compile on mono
1.9.1.  (Note there is no 1.9.1 version in bugzilla).

--- input.xml ---
<?xml version="1.0" encoding="utf-8"?>
<foo>
    <bar id="id1"/>
    <bar id="id2"/>
</foo>

--- transform.xslt ---
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
        <xsl:param name="doc" select="document('')"/>
        <xsl:template match="/">
                <xsl:choose>
                        <xsl:when test="$doc or
count($doc)>0"><xsl:text>Document found</xsl:text></xsl:when>
                        <xsl:otherwise><xsl:text>Document not
found</xsl:text></xsl:otherwise>
                </xsl:choose>
        </xsl:template>
</xsl:stylesheet>

---main.cs ---
using System;
using System.Xml;
using System.Xml.Xsl;

namespace XslDocumentTest
{
        class MainClass
        {
                public static void Main(string[] args)
                {
                        XslCompiledTransform xslTransform = new
XslCompiledTransform();
                        XsltSettings settings = new XsltSettings();
                        settings.EnableDocumentFunction = true;
                        xslTransform.Load("transform.xslt", settings, new
XmlUrlResolver());
                        xslTransform.Transform("input.xml", "output.xml");
                }
        }
}
--- expected result ouput.xml ---
<?xml version="1.0" encoding="utf-8"?>Document found

--- result of mono XslDocumentTest.exe ---
