Is it possible to add a textarea in the development SSP IdP in order to be able to test the flow of Stepupup components that are based on certain SAML attirbutes?

Personally I would prefere a textarea were a JSON string that can be set n the login page so you would be able to add SAML-attributes to the SAML-response received by the components and therefore are able to test certain things with the Behat tests in Devconf.

The main goal of this is to increase the testcoverage. For example for: OpenConext/OpenConext-devconf#17

It's just a suggestion and nothing is set in stone, so feel free to open up a discussion.
