Is anybody able to fix it. It is an official OGF mailing list so someone
should be responsible for it.

The attribute interface does have an exception "DoesNotExist". However
my problem is that the main spec says in section 3.5.3 (in the version I
printed) that non-optional attributes must have a default value. In this
case I would like to say that the parameters are read only, non-optional
and that if they are not present an exception will be thrown. However
this does not appear to be possible.

That sounds - I will add "DoesNotExist"
