SQL Developer Data Modeler

I need to be able to create an external "data dictionary" to show to database users. I am currently exporting to a reporting schema, and then writing SQL against the reporting schema to get table, column, datatype, etc... information. I also need to be able to get the column and table comments that I entered into data modeler. I can't find those anywhere in the reporting schema. Are they included in the reporting schema? If not, how do I export those comments from data modeler?
Thanks,
Jonathan
