Enabling users of assistive technologies to find their way through web content requires embedding semantic metadata about web document structural divisions. This is particularly important for structural divisions of long-form documents and goes along with embedding semantic metadata about web-application widgets and behaviors for assistive technologies. This specification defines a set of WAI-ARIA roles specific to helping users of assistive technologies navigate through such long-form documents.
This document is part of the WAI-ARIA suite described in the WAI-ARIA Overview.

The primary aim of the Digital Publishing WAI-ARIA Module 1.1 is to address some bugs discovered since the release of the original module. These fixes are mostly minor in nature – ranging from simple typos in the text and examples, to some issues around how accessible names are computed.
There are a couple of significant changes proposed in this revision to be aware of, however. They are:

WAI-ARIA is a technical specification that defines a common host language semantic accessibility API and framework that enables web browsers to map the accessibility semantics in web content to platform-specific accessibility APIs. This enables web content to be interoperable with platform assistive technologies similar to native platform applications without platform dependencies.
This specification is a modular extension of WAI-ARIA designed for the digital publishing industry. The goals of this specification include:
The roles defined in this specification are derived from the EPUB Structural Semantics Vocabulary.
For a more detailed explanation of WAI-ARIA please refer to the WAI-ARIA Introduction and how it applies to Rich Internet Application Accessibility.
This specification defines a module of WAI-ARIA for digital publishing, including roles, states, properties and values. It impacts several audiences:
Each conformance requirement indicates the audience to which it applies.
Although this specification is applicable to the above audiences, it is not specifically targeted to, nor is it intended to be the sole source of information for, any of these audiences. In the future, additional documents will be created to assist authors in applying these WAI-ARIA semantics for the publishing industry and to define how the information in this document is mapped to platform accessibility APIs.
This module builds on the general User Agent support principles defined in [WAI-ARIA] by also providing the ability for user agents to enhance the general user interface presented to readers.
The Digital Publishing WAI-ARIA module follows the model for co-evolution of WAI-ARIA and host languages defined in [WAI-ARIA]. It is intended to augment semantics in supporting languages like [HTML], [SVG2] and EPUB, or to be used as an accessibility enhancement technology in other markup-based languages that do not explicitly include support for ARIA. It clarifies semantics to assistive technologies when authors create new types of objects, via style and script, that are not yet directly supported by the language of the page, because the invention of new types of objects is faster than standardized support for them appears in web languages.
It is not appropriate to create objects with style and script when the host language provides a
semantic element for that type of objects. While WAI-ARIA can improve the accessibility of these objects, accessibility is best provided
by allowing the user agent to handle the object natively. For example, it is not better to use a
heading
role on a div
element than it is to use a native heading
element, such as an h1
.
It is expected that, over time, host languages will evolve to provide semantics for objects that currently can only be declared with this specification. This is natural and desirable, as one goal of WAI-ARIA is to help stimulate the emergence of more semantic and accessible markup. When native semantics for a given feature become available, it is appropriate for authors to use the native feature and stop using this module for that feature. Legacy content may continue to use the Digital Publishing WAI-ARIA module, however, so the need for user agents to support it remains.
While specific features of this module may lose importance over time, the general possibility of the Digital Publishing WAI-ARIA module to add semantics to web pages or open web-based standards, such as EPUB, is expected to be a persistent need. Host languages may not implement all the semantics this module provides, and various host languages may implement different subsets of the features. New types of objects are continually being developed, and one goal of this specification is to provide a way to make such objects accessible, because authoring practices often advance faster than host language standards. In this way, this module and host languages both evolve together but at different rates.
Some host languages exist to create semantics for features other than the user interface. For example, SVG expresses the semantics behind production of graphical objects, not of user interface components that those objects may represent. Host languages such as these might, by design, not provide native semantics that map to this specification's features. In these cases, the Digital Publishing WAI-ARIA module could be adopted as a long-term approach to add semantic information to these host languages.
Programmatic access to accessibility semantics is essential for assistive technologies. For more information, refer to the Assistive Technologies section in [WAI-ARIA].
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
The key words MAY, MUST, MUST NOT, and SHOULD in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
Normative sections provide requirements that authors, user agents and assistive technologies MUST follow for an implementation to conform to this specification.
Non-normative sections provide information useful to understanding the specification. Such sections may contain examples of recommended practice, but it is not required to follow such recommendations to conform to this specification.
This section defines additions to the WAI-ARIA role taxonomy and describes the characteristics and properties of all roles. See ARIA Roles for descriptions of the fields provided by this module.

The doc-biblioentry
role was designed for use as a list item, but due to clarifications in the WAI-ARIA
specification, it is not valid as a child of the list

(role)A separator denoting the position before which a break occurs between two contiguous pages in a statically paginated version of the content.
Page break locators are also commonly used to provide static markers in purely digital publications (i.e., where no statically paginated equivalent exists). These markers provide consistent navigation regardless of differences in font and screen size that can otherwise affect the dynamic pagination of the content.
Authors MUST ensure the name of the page break is an end user-consumable page number that identifies the page that is beginning so that assistive technologies can announce the page as needed (e.g., in a command to identify the current page).
doc-pagelist

MUST NOT contain the doc-pagebreak

doc-pullquote
(role)A distinctively placed or highlighted quotation from the current content designed to draw attention to a topic or highlight a key point.
Unlike a passage quoted from another source, a pullquote is a direct repetition of text in
the current document. As a result, authors must ensure that the presentational occurrence is
hidden from users of assistive technologies (e.g., using the aria-hidden
attribute).
The following example shows the identification of a pullquote that will be presented elsewhere (e.g., via a script). In this case, the pullquote is not hidden as the marked text is not presentational.
<p>… I may die, but first you, my tyrant and tormentor, shall curse the sun that gazes on your misery.
<span id="pq01" role="doc-pullquote">Beware, for I am fearless and therefore powerful.</span>
I will watch with the wiliness of a snake, that I may sting with its venom. … </p>
The next example shows a pullquote that duplicates the text. This quote is hidden because it is for presentational purposes only.
<p>… Better habits pave the way to growth, and growth leads to greater happiness.</p>
