Of course.

I understand this question as a crossLink table's Primary Key could
easily be the combination of the two foreign keys. However, since
DB_DO doesn't wupport multi-field keys and FormBuilder also hasn't
been build with this in mind we still require a single-column primary
key. I would suggest, as always before, an auto incremented id primary
key with an additional unique constraint on the two foriegn keys.
