Complex lists address complex needs. Examples include multi-party signature blocks with multiple signers for each party, wills and trusts with inter-related roles, product families with complex sibling or parent/child arrangements or mixtures of styles, colors, features, and parts numbers.

This example steps through the process of defining relationships in such a way that the document can engineer its own future alternatives accurately and quickly. The lesson takes to heart the best practice that the form author should invest time and thought to "getting it right" so that future users can benefit in both speed and the elimination of errors.
