Thanks for information. We were not aware of the WS-Inspection effort. 
 The defined format looks interesting and bears watching.  I am not a 
fan of the publication/discovery method they describe in section 6 
however.  As I'm sure you realize we specifically crafted our 
architecture so that it could support efforts like this, RDDL and other 
metadata aggregation formats without having to choose a winner. 
 WS-Inspection asks users to look around the interested URL for an 
inspection.wsil document.  This feels messy and error prone because the 
standard does not guarantee where to find the document but instead asks 
the publisher to scatter the inspection document to whereever they think 
a user might look for it.  Of course it also presumes that a wsil 
document is THE answer.

Thanks for your comments,
