I don't know the breakdown of workshops for CSA v. ASA (the program should be posted real soon).
MS (or before that, NOMSV) conferences have always targeted survivors, partners, professionals who work with them and professionals who are survivors themselves.
It's generally a good mix and some workshops are geared for survivors only, or professionals only, but there are a lot (if not most) for both audiences.
I'm doing two for both audiences, "Disclosure and Confrontation" as well as "Breaking the Cycle of Self-Defeating/Self Destructive Behaviors". I've been going to these conferences for probably 20 years or more (can't remember when they first were done, but I've only missed Orinda in the 90's). They are well worth the trip.
Safety is paramount and we always have safe rooms with a professional to cover anyone who gets upset.
