Oracle 10g diff on 2 schemas [FK issue]

Hello

I’m diffing two schemas in Oracle 10g using Liquibase 2.0.1 plus the ojdbc6.jar thin driver.

My problem:

all works fine, but foreign keys are defined in the schema where I’m diffing FROM.
I need a neutral (schema independent) definition.

How can I achieve that?
Am I doing something wrong?
