Issue 6401: XSLT for transforming wse:EventDescriptions to an Event Sink WSDL

Hey all,

You may remember that, during the discussions of our proposal for 6401 
[1] at the last F2F, I mentioned several times that it would be 
'relatively easy' to write an XSLT that transformed a 
wse:EventDescriptions element into a WSDL document that described the 
Event Sink interface for Raw Notifications of the Events described in 
the EventDescriptions? Attached is an XSLT 2.0 stylesheet that does just 
that, along with a sample EventDescriptions document and the Event Sink 
WSDL that is generated from that document.

This illustrates the following points:

1.) The data model for EventDescriptions contains the necessary 
information to generate an Event Sink WSDL.

2.) The rules defined in Appendix F of our proposal are sufficiently 
rigorous to permit the independent implementation tools that transform 
an EventDescriptions to an Event Sink WSDL that correctly describes the 
corresponding Raw Notifications. People shouldn't take my word for this. 
They should look at the attached EventsToWSDL.xsl (which has been 
documented to point out which rules are being implemented by which 
templates) and make sure there is no "secret sauce" that isn't described 
in Appendix F.

3.) The implementation of such a tool is, indeed, relatively easy. It 
took me about 6-7 hours to write this stylesheet with some help from 
Tom, Doug, and Bob. Keep in mind that I tend to write one XSLT about 
every two years or so and that much of this time was spent reading Doug 
Tidwell's "XSLT, 2nd Edition".
