Quality aspects of Web Services

Hi everybody,

I'm trying to write a survey about modeling quality aspects of services 
in the context of Web Services world. The problem I met is the lack of 
documents and papers related to this topic. The only effort that seems 
to be going in this direction is the announced WSEL from IBM. But, at 
the moment, nothing has been published.

From the proposed draft charter for Choreography WG,  quality aspects 
are declared to be out of scope. I would like to receive some 
clarification about:

1. are quality aspects of web services issues going to be included in 
some W3C-WS activity?

2. what the current status and roadmap of WSEL (if known)?

3. can you provide for any kind of links about this topic? (papers, 
proposed langauges, etc.)

Thanks,

regards,

Sergio
