Just found the Authorization Identity control (RFC3829). So another,
much cleaner solution would be just to define that interaction between
the VC exop and this control similarly as its interaction with the Bind
request. This should preserve full compatibility with existing
Master branch also seems to have an overlay implementing this, I will
have a look what is needed to get support for this in the VC overlay.
