One of the major forces guiding our design efforts has been the desire to create well-formatted printed documents from material in a KMS database. Since frames provide a local WYSIWYG view, there is a natural process for composing the document: concatenating the contents of frames from a hierarchy in depth-first order. This document composition program can be invoked at any level of a hierarchy of frames, thereby enabling users to get just the portion of a document they want.
