Answer 1

You can use DiscriminatorFormula:

// Base class
@DiscriminatorFormula("case when value in ('ACT','DNR','ATT') then 1 
   when 'OTH' then 2 else 3 end")

// Subclass 
@DiscriminatorValue("1") // maps to ACT, DNR, ATT

Answer 2

A subclass has exactly 1 discriminator value.

You can add additional subclasses under the existing subclass for the extra discriminator values. Subclasses need not have additional properties or behavior.
