+Summary: Xslt processor expects ArrayList parameter when calling extension object method
+
+Description of Problem:
+-----------------------
+On mono 0.25, when the xslt processor calls a method from an extension 
+object, an exception is thrown if the method's parameter is not 
+System.Collections.ArrayList.
+
+On the .NET Frameowrk 1.0 or 1.1, methods with other types of parameters 
+can be called from the xslt.
+
+
+Steps to reproduce the problem:
+-------------------------------
+1. save the source code at the end of this message on your disk as 
+XsltBug.cs
+
+2. enter:  mcs -t:exe -out:XsltBug.exe XsltBug.cs
+
+3. enter:  mono XsltBug.exe
+
+
+Actual Results:
+---------------
+Unhandled Exception: System.Xml.XmlException: No applicable function for 
+Process
+This takes (System.Collections.ArrayList)

+
+
+Expected Results:
+-----------------
+The correct result is obtained when run on the .NET Framework:
+
+                Items:
+                @name=plop,
+                @name=glop,
+
+
+How often does this happen?
+---------------------------
+Always
+
