really wysiwyg xsl editor

Does anyone know of a very user friendly wysiwyg xsl editor, i.e. one which
can be used to create report templates by non-IT people.  I have had a quick
look at the MoreMotion and Stylus Studio options but they still seem to be
for IT people.  Please also let me know if you have done an exhaustive
search for a wysiwyg XSL editor for non-IT users and not found any.

Thanks

Kate
