As I said during the first mention of Privacy in the security
threads, protecting the privacy of data from unintended
readership pertains to Confidentiality, which is of security.
 (The security primitive for addressing Confidentiality is Encryption.)
The rest are non-security-related Privacy.  (There's in fact no known
security primitive to address any of them.)
I too am of the opinion that how data is treated by apps
should be ruled out of scope, though I'd always keep my mind
open to new revelations about Privacy pertaining to the WG's
goals, including the one newly proposed by Hugo.

	Privacy consists of the right of an entity, normally a person, acting in
	their own behalf, and how much it will interact with its environment. The
	entity determines how much information to share.
	This also has implications for web services in how to keep web services
	confidential, this should be part of security. How the data is treated in
	the application using web services is I think beyond the scope of the
	architecture group

	Privacy can be protected by, for example:

	I don't think we can prevent data collection, but we can have services
	advertize what they are doing, e.g. by using P3P, which was developed
	at W3C[1], and plan for such things in the architecture.

	Even though I have been the one advocating for privacy, I am no
	privacy expert and am copying Rigo Wenning on this in case he wants to
	add something.
	To me, privacy in the Web services architecture context is about
	collection of data by service providers about the service consumers;
	the tricky part is that there could be several parties involved for
	providing a complex service, which could each have different policies.
	The data could be tied to your name, address, or maybe simply a user
	identifier, for marketing purposes or maybe just for statistical
	analyses, it could be shared among providers or kept to one provider,
