See my statement about SPs deployed in the wild choking on such
metadata. It's not simply a question of "updating schemas" for a few
(or only one) federation operator:

This stuff breaks deployments in the wild and the Shibboleth SP
(should it be the only one) is probably the most often used SAML
implementation on the globe. So -- contrary to what Davide said -- I'm
very happy old schemata were used in the software I had at hand
otherwise we would only have found out about that in a few days (or
weeks) once Shib SP admins all over the world started asking their
local federation operator why their SP doesn't know any IDPs anymore.

"People should just update their software so that we can support
corner cases noone ever asked for" is a possible approach to such
scenarios. It's certainly not my preferred one, though.
