Growing Pains

Growth by accretion has resulted in some content models that are at best odd and at worst broken in pretty obvious ways.

Ten years of incremental growth has also changed the scale of DocBook. Designing a schema of roughly 400 elements is different than designing a schema of roughly 100. Logically extending decisions that looked regular and consistent when DocBook had 100 elements has not always resulted in a design that continues to look regular and consistent.
