OJB XDoclet generating torque table schema

[Reggie & Valerie Hayes]

I am using the xdoclet ojb module to generate an ojb repository and a
torque schema.  The problem that I am running into is that the foreign
key reference constraints are not generated for ojb collections within
the torque schema.  The foreign key reference constraints are generated
for ojb references.  Am I doing something wrong?
