/*! \brief Notification of the creation of an identity

    This should be considered just a notification.  The identit
    provider does not have an opportunity to veto the creation of an
    identity whose name has been found to be valid.  However, when
    handing this notification, the identity provider can:

    - Change the flags of the identity and/or marking the identity as
      invalid.

    - Change the default identity.

    Note that this notification is sent before the general :;KMSG_KCDB
    notification of the identity creation is sent.

    Message parameters:

    - \a uparam : Not used.

    - \p vparam : handle to the identity
