Yes
That is one of the nice things about the CFPropertyList is that it is keyed
- the Save/Restore state have the basic support that we would like all AU to
support - but any additional information is totally up to you to provide and
support (and overiding the virtual call is a fine way to go)
The AUBase calls will ensure that the data matches the AU (ie. right data,
right AU) - so when restoring you should probably call that first before
doing your own work.
