+Atsushi, I think there's a regression here as I do not get the 
+correct results on Mono.
+
+Expected result:
+
+Title : A Brief History of Time
+        left() : A Bri
+        right() :  Time
+Title : Principle Of Relativity
+        left() : Princ
+        right() : ivity
+
+Actual result:
+
+Title : A Brief History of Time
+        left() :
+        right() :
+Title : Principle Of Relativity
+        left() :
+        right() :
+
+I traced the issue down to the following code in 
+System.Xsl.XsltContext:
+
+public abstract IXsltContextFunction ResolveFunction (string prefix, 
+string name, XPathResultType [] argTypes);
+public abstract IXsltContextVariable ResolveVariable (string prefix, 
+string name);
+
+...
+
+internal virtual IXsltContextVariable ResolveVariable 
+(XmlQualifiedName name)
+{
+  return ResolveVariable (name.Name, name.Namespace);
+}
+		
+internal virtual IXsltContextFunction ResolveFunction 
+(XmlQualifiedName name, XPathResultType [] argTypes)
+{
+  return ResolveFunction (name.Name, name.Namespace, argTypes);
+}
+
+In both internal methods, the string representation of the QName is 
+passed as prefix and the namespace is passed as name.
+
+These methods are used in ExprVariable.Evaulate and 
+ExprFunctionCall.Evaluate.
