I'm writing to express concern over Section 6 [1] being put at risk. I know of multiple implementations of Section 6 [1] for which I count at least 8 companies that provide product support and for which interop has been demonstrated. Section 6 [1] is a key enabler of a number of integration and interop scenarios relating to the expression and discovery of constraints and capabilities associated with a service and its endpoint(s).  

If it's a matter of participating in an interop session, I see no reason why we can't get a number of interested parties involved. 

Why is W3C putting [1] in question?

Subject: RE: Features at Risk: Attaching Policies Using UDDI

I would be opposed to keeping the "c) Attaching Policies Using UDDI" at risk.

To address the concern that "thus far, there aren't any publicly 
visible implementations," I would point out that most deployments of 
UDDI are private and not publicly available.

Most UDDI implementations provide a browser-based interface to CRUD 
UDDI entries.  Such an interface is sufficient to manually add the 
UDDI entries or tModels that reference policies in accordance with 
WS-PolicyAttachment.  So, you may find entries in private UDDI 
registries that refer to policies in accordance with 
WS-PolicyAttachment.  I have added the three category tModels defined 
in Appendix B to a UDDI server that is within MITRE, so these 
"taxonomies" are available to use.

I can see there being an issue with "merging" into an "effective 
policy", but the ability to reference policies from UDDI in a 
standard way is of value.
