<!--
the write_sql attribute enables us to indicate where table
references exist, but we don't want them to be defined by an
actual FOREIGN KEY constraint in the DB. This will enable the
API to have a getter method for this value, but it just wont'
have a constraint in the DB.
the can_self_reference attribute is for those cases when a table
has a foreign key to itself, and that foreign key is permitted
to point to the same object. For example, this happens when
groups are used for setting permissions, and the groups themselves
have a group that defines the permissions for who can add or delete
members from the group.
