Within a WordprocessingML document, settings specify stored preferences which shall be used when processing the contents of the document. These settings are typically divided into three categories:

  • Document Settings - settings which influence the appearance and behavior of the current document, as well as store document-level state.

  • Compatibility Settings - settings which tell applications to perform behaviors which are designed to maintain visual output of previous word processing applications. These settings are for backward compatibility and are all ignorable.

  • Web Settings - settings which affect how this document shall be handled when it is saved as HTML. These settings exist primarily for backward compatibility reasons and are all ignorable.

The first two groups are stored in the Document Settings part, and the last group is stored in the Web Settings part.
