> I don't expect entity-auto to handle every possible situation. I'd suggest we 
> keep it simple and 80-20 rather than fiddle with it forever.
> There's an error message if you try to push it too hard which lists what it 
> can do:
> "1. a single OUT pk for primary auto-sequencing, " +
> "2. a single INOUT pk for primary auto-sequencing with optional override, " +
> "3. a 2-part pk with one part IN (existing primary pk) and one part OUT (the 
> secondary pk to sub-sequence), " +
> "4. a N-part pk with N-1 part IN and one party OUT only (missing pk is a 
> sub-sequence mainly for entity assoc), " +
> "5. all pk fields are IN for a manually specified primary key");
> So it can deliver one new id in an out parameter, but not more than one. I 
> can live with that. For more complex situations, we can write a service 
> rather than use entity auto.
> {quote}
> I suggest we document it in services.xsd and the [Service Engine 
> Guide|https://cwiki.apache.org/confluence/display/OFBIZ/Service+Engine+Guide],
>  explaining what the possiblities are based on the message above. BTW I had a 
> look at services.xsd and it's not yet documented enough.
