+Summary: No XPath.Context bound in XmlNode.SelectNodes
+
+Don't know if this really is a bug, since I didn't come to check against
+.NET yet. But it appears line no XPath.Context bound in
+XmlNode.SelectNodes. As a result no XPath functions are available for the
+XPath expressions passed to XmlNode.SelectNodes.
+
+
+Steps to reproduce the problem:
+
+using System;
+using System.Xml;
+
+class SelectNodesTest
+{
+    public static void Main()
+    {
+        XmlDocument xml = new XmlDocument();
+        xml.LoadXml("<root><node argument='foobar'/></root>");
+
+        foreach(XmlNode node in xml.SelectNodes
+            ("//node[substring(@argument, 1, 3) = 'foo']"))
+        {
+            Console.WriteLine("match: {0}", node);
+        }
+    }
+}
+
+Actual Results:
+
+[mathias@dali tmp]$mcs SelectNodesTest.cs && mono SelectNodesTest.exe
+Compilation succeeded
