This message should I think be followed by the name of the parameter that you haven't supplied. This will typically be a global <xsl:param> element (or in XQuery, a global "declare variable.. external"). At the point where this message is generated, there's no line number available, so you will have to find the offending xsl:param the hard way.

                I’m getting this message when running my set of XSLs within my own .Net implementation, but no line numbering or filename


‘No value supplied for required parameter’


Any idea how to turn on line numbering or extract it form the Exception thats thrown?
