L.1.14.1 Introduction

An annotation is one of various kinds of supplementary markup, which can be stored inside or around a region of text within the document’s contents. The kinds of supplementary information stored within a document can include comments (L.1.14.5), revisions (L.1.14.7), spelling and/or grammatical errors (L.1.14.10), bookmark information (L.1.14.8), and optional editing permissions (L.1.14.9).

Within a document’s contents, annotations are stored in one of three different forms:

Inline Cross-Structure Properties

These three forms are needed in order to maintain compatibility with both the legacy annotations functionality of current word-processing applications and the requirements of an XML-based format (i.e., well-formedness of the resulting XML markup). These three forms are referenced within the individual annotation types described in subclauses L.1.14.2 through L.1.14.4.
