Body:
I recently wrote a custom persister that allowed this. I allowed lists (13,14), ranges (20-31), plus greater than and less than options.
Basically I allowed a comma-separated list in the discriminator and created a custom type to map the discriminator as a string. Then, inside my custom persister I converted this to numeric values and stored my own mapping of discriminator to subclass

Key: HB-172
Summary: multiple discriminator-value for subclass
Type: New Feature
Status: Unassigned
Priority: Minor
Project: Hibernate2

Description:
It would be nice to allow a class or a subclass to have multiple possible discriminator values.
Hibernate would need to map the same subclass to multiple values and the resulting unmapped values to the root class (or some other subclass), using a mapping that could look like this:
<class name="pkg.RootObject" table="SOME_TABLE" discriminator-value="*">
...
<discriminator column="TYPE" type="integer" />
...
<subclass name="pkg.SubClassA" discriminator-value="12, 13">
<subclass name="pkg.SubClassB" discriminator-value="45">
</class>
