Clearly consent has its uses. I am just saying it isn't always appropriate and I have not yet seen a convincing counter-argument to what Andrew has been saying for some time now.

Remember we don't only talk about public SP's serving public IdPs here, but also commercial ones, in other countries (you heard about the Internet, rigtht?) etc. There is much more to it than what the IdP thinks is most convinient or deem 'nessecary'. Hence the jungle - which in all cases, so far, is covered by user-consent. And hence the (DK) consensus that user-consent is the way to go, not at least as a principle cautiousness in what all recognize as the 'early days of federations' where personal information is used for authorization in changing security domains.

The suggestion has been to welcome the user at the SP with information about the PI recieved and the purpose description.
