• Attributes with NSNumber as a value class have a value type defined.
• That attributes with a custom value class have a value factory method and a adaptor value conversion method set.
• The source attributes of a relationship that propagate primary keys contain the source entity's primary key attributes; that the destination attributes contain the primary key attributes of the destination entity, and that the inverse relationship doesn't also propagate primary key.

• All the attributes in the parent entity exist in the child.
• The relationships in the parent exist in the child, and their relationship definitions match.
• The primary key definition in the parent matches the primary key definition in the child.
• The parent and child have restricting qualifiers if their columns reside in the same table.

• All relationships have at least one join defined.
• The destination attributes of to one relationships are the primary keys of the destination entities.
• The source attributes of a relationship that propagate primary keys contain the source entity's primary key attributes; that the destination attributes contain the primary key attributes of the destination entity, and that the inverse relationship doesn't also propagate primary key.
