The XSL standard defines extension elements and provide the 
extension-element-prefixes attribute. 

The "Microsoft XML core services (MSXML) 4.0" help file on <xsl:stylesheet> 
attributes, documents "extension-element-prefixes" as follows:

"The namespace to be used as an extension namespace. The value is a 
white-space-separated list of namespace prefixes. The namespace bound to each 
of the prefixes is designated as an extension namespace."

I have tried both MSXML 4.0 and MSXML 6.0 with the same results.
