+Summary: XslTransform.Transform - incorrect encoding when outputting to a FileStream
+
+Description
+-----------
+
+When 'Transform(XPathNavigator input, XsltArgumentList args, Stream output)'
+overload of the 'System.Xml.Xsl.XslTransform' class is used,
+the 'encoding' attribute of the 'xsl:output' directive is ignored.
+
+Some other overloads of this method - 
+'Transform (string inputfile, string outputfile)'
+in particular - are not affected.
+
+
+Steps to reproduce
+------------------
+
+The following code fragment exhibits this problem.
+
+==== test-xslt-encoding.cs
+using System.IO;
+using System.Xml;
+using System.Xml.Xsl;
+
+class TestXsltEncoding
+{
+  public static void Main()
+  {
+    XmlDocument xd = new XmlDocument();
+    XslTransform xslt = new XslTransform();
+    Stream fs;
+
+    xslt.Load("test.xsl");
+
+    // Use simple Transform - result is OK
+    xslt.Transform("test.xml", "out-simple.xml");
+
+    // Use FileStream - uses UTF-8
+    xd.Load("test.xml");
+    fs = new FileStream("out-fs.xml", FileMode.Create);
+    xslt.Transform(xd, null, fs);
+    fs.Close();
+  }
+}
+====
+
+==== test.xsl
+<?xml version="1.0"?>
+<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
+
+  <xsl:output encoding="ISO-8859-2" />
+
+  <xsl:template match="/">
+    <output><xsl:apply-templates /></output>
+  </xsl:template>
+
+</xsl:stylesheet>
+====
+
+==== test.xml (
+<?xml version="1.0"?>
+<test>&#261;</test>
+====
+
+
+Actual Results
+--------------
+
+'out-simple.xml' uses encoding specified in test.xsl,
+'out-fs.xml' is encoded in UTF-8.
+
+
+Expected Results
+----------------
+
+Both files 'out-simple.xml' and 'out-fs.xml' should use
+the same encoding specified in test.xsl. 
+
+
+How often does this happen?
+---------------------------
+
+Always
+
+
+Additional Information
+----------------------
+
+The following patch seems to correct this problem (at least for the
+managed XSLT implementation).
