back in the early days we thought of the use of just one single profile.
And we missed the opportunity to drop the Profile attribute completely
when we introduced AdditionalProfiles.

Pim already pointed out this inheritance problem. Nevertheless, if the
requestor does not mandate a profile, the server must have the chance to
respond without a Profile attribute. Or we apply the Null pattern and
define an URN for a 'NoProfile' profile ...
