The DITA architecture makes use of schema design patterns to derive new XML vocabularies from existing vocabularies. An alternative method for deriving DITA vocabularies is to rely on the simplying principle of conserving the base design except where explicitly overridden. Because the base vocabulary supplies a structural scaffold, a specialized design requires only vocabulary documentation and an annotated example. This focus on explanation and use rather than on grammar allows the people with the need to create a solution. The talk will explore the work in progress on this approach including limitations and considerations such as dependency management.
