I'm trying to figure out how to add my own XSLT extensions to be used in the DataFormWebPart on MOSS 2007, kind of like a custom ddwrt library.
A comment on this post seemed to say that I could register my own assembly in the pages/Controls section of my web.config, and then use the functions in my XSLT.
I tried doing it but my DFWP just keeps throwing an error in SharePoint Designer saying "Namespace Mycompany.Customxsltextensions contains no functions".
Is it possible to add custom XSLT extensions thru the web.config? Is there any documentation on this?
