That does not require an XSLT processor to actually support implementing 
extension elements.

Well that is part of the XSLT reference in the MSXML documentation, also 
online here
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/abe65eb5-eea5-4874-936c-6602132eb2eb.asp>
If you compare that to <http://www.w3.org/TR/xslt#extension> then you 
see where that description of the attribute comes from. Only a 
description of the attribute does not imply there is mechanism for MSXML 
to implement extension elements.

As said, MSXML has msxsl:script as its own extension element to then 
define your own extension functions, but to my knowledge it does not 
allow you to implement your own extension elements.
