+Summary: XslTransformation extension objects
+XSLT extension objects are as yet unimplemented. Attached to this, if I
+can figure out how to do that, is a patch to implement them.
+The patch modifies mcs/class/System.XML/System.Xml.Xsl/XslTransform.cs
+If extension objects are not used by the user, then the behavior of
+XslTransform is unchanged, so working things won't break. This isn't a
+complete implementation, but it's a working start.
+Known issues with patch:
+ requires -unsafe keyword (XPath only returns pointers to XSLT objects)
+ the signatures of methods in extension objects must match exactly to the
+types of parameters that the method is called with from the stylesheet
+(this is fixable but takes more work). The MS documentation examples
+indicate that parameters can be converted between types (ie double =>
+decimal) as necessary.
+ node set parameters are converted to an ArrayList of strings, since there
+isn't a good way to pass the actual nodes to the extension functions
+ I added a Mono-specific feature of registering the static methods of a
+type as extension functions (ie System.Math's methods), which I don't think
+can be done in MS .NET. This is useful for me for something else I'm
+I used this patch to write a Mono version of the xsltproc tool which I'm
+using to update existing Mono XML documentation files for the monodoc
