Hugo,

Frankly I could happily and still can live with
the original wording of D-AR020.5.
It floated quite naturally, as opposed to the
"new and improved" version, which comes across
as, well: overworked. :-)

Joseph asked me to champion AC020[1].

At the last face-to-face meeting[2], we accepted AC020, AC020.1,
AC020.2, AC020.3, rejected AC020.4, and proposed AC020.5

I would like to request two minor editorial change:
- AC020.3: I was told that it was better to use "user" instead of
  "consumer", because it was more general (at least in US law):
|          + AC020.3 The Web Services Architecture MUST enable a user
|            to access a Web Service's advertised privacy policy
|            statement.
- it seems that AC020.[1235] are more requirements than CSFs; it
  probably would be better to name them AR020.[1235].

So we need to get consensus on the proposed D-AC020.5 (or D-AR020.5).
The text reads:

|          + D-AC020.5 The Web Services Architecture MUST enable
|            delegation and propagation of privacy policy.

This requirements is trying to address the following problem: a Web
service A may use other Web services to fulfill a request. If a user U
and A do business based on a particular privacy policy P, any Web
service contacted by A in order to process U's request should not
violate P.

This is why P should be propagated along with any processing.

People seemed generally happy about this idea at the face-to-face
meeting, but I had echoes on the security task-force call that the
wording was obscure.

Maybe it comes from "delegation", which is actually confusing me too.
What about (two choices):

  The Web Services Architecture MUST enable propagation of privacy
  policy [during delegation of processing | across Web services].

Well, it's not crystal clear either, but we can use that as a starting
point.

Regards,

Hugo
