Yes and no. The discriminator field is an internal Hibernate
mechanism. It determines which concrete subclass of Annotation will be
generated. These values can be seen in:

    components/model/resources/mappings/annotations.ome.xml

but are in no way available to the client.

No. It would be necessary to update the annotations mapping file and
regenerate all the client code and the database. At that point, you've
created your own distribution which will not work with other OMERO
installations. However, if the annotation type you need is of general
use, then we'd certainly be very interested in possibly adding it to
trunk.
