Systems and methods for document processing are discussed herein. In certain embodiments, novel document processor programs may allow for a knowledge worker to concentrate on the content of a document, rather than its formatting. Such programs may separately store layout and/or typesetting information from content, allowing for their combination after the content is created. Novel data structures and techniques are provided to permit the use of advanced version control, collaboration techniques and team/or workflows. User interfaces are also disclosed which dynamically adapt to a document type and/or a portion of a document being edited. Such features may significantly increase knowledge worker drafting efficiency.
