The PLS document filename SHOULD use the file extension .pls.
Document Properties
It MUST be valid to the RELAX NG schema for PLS documents available at the URI https://www.w3.org/TR/2008/REC-pronunciation-lexicon-20081014/ [PRONUNCIATION-LEXICON].
PLS documents MUST be represented and located as defined in EPUB Package — Conformance [Packages32].
PLS documents MUST meet the content conformance criteria defined in PLS Documents — Content Conformance.
The link element hreflang attribute SHOULD be specified on each link, and its value MUST match the language for which the pronunciation lexicon is relevant [PRONUNCIATION-LEXICON] when specified.
PLS documents MUST be associated with the XHTML Content Document to which they apply using the [HTML] link element with its rel attribute set to "pronunciation" and its type attribute set to the media type "application/pls+xml".
PLS Documents MAY be associated with XHTML Content Documents. Each XHTML Content Document MAY contain zero or more PLS document associations.
Fixed Layout Documents
For SVG Fixed-Layout Documents, the ICB dimensions MUST be expressed using the viewBox attribute [SVG].
For XHTML Fixed-Layout Documents, the initial containing block [CSS2] dimensions MUST be expressed in a viewport meta tag using the syntax defined in [CSS-Device-Adapt-1]. In this version of this specification, only the width and height expressions MUST be recognized by Reading Systems.
Reading Systems SHOULD NOT inject additional content such as border, margins, headers or footers into the Viewport.
When rendering Fixed-Layout Documents, the default intent is that the Content Display Area SHOULD occupy as much of the available Viewport area as possible.
It MUST specify its initial containing block [CSS2] as defined in Initial Containing Block Dimensions.

CONFORMANCE
The XHTML Content Document filename SHOULD use the file extension .xhtml
It MAY include extensions to the [HTML] grammar as defined in HTML Extensions, and MUST conform to all content conformance constraints defined therein.
For all document constructs used that are defined by [HTML], it MUST conform to the conformance criteria defined for those constructs in that specification, unless explicitly overridden in HTML Deviations and Constraints.
It MUST be an [HTML] document that conforms to the XHTML syntax.
Multimedia
Media Overlay Documents (smil)
CONTENT (In this order): 1) head [0 or 1] 2) body [exactly 1]
*body
clipEnd
A clock value that specifies the offset into the physical media corresponding to the end point of an audio clip. MUST be a [SMIL3] clock value.
clipBegin
A clock value that specifies the offset into the physical media corresponding to the start point of an audio clip. MUST be a [SMIL3] clock value.
The audio element is OPTIONAL only if its sibling text element refers to audio or video media (see Embedded Media), or to textual content intended for rendering via Text-to-Speech (TTS).
*text
The text element references an element in the EPUB Content Document. A text element typically refers to a textual element, but can also refer to other EPUB Content Document media elements (see Embedded Media).
NO CONTENT
*src
The par element contains media objects which are to be rendered in parallel.
seq
The seq element contains media objects which are to be rendered sequentially.
IMPORTANT: At least one par or seq is required

CONSTRAINTS
The Media Overlay Document filename SHOULD use the file extension .smil.
It MUST be packaged with the EPUB Publication as shown in Packaging.
It SHOULD use semantic markup where appropriate, as described in Semantic Inflection.
It MUST adhere to the requirements for Embedded Media.
It MAY refer to more than one EPUB Content Document, but an EPUB Content Document MUST NOT be referenced by more than one Media Overlay Document.
It MUST be authored to reflect the structure of the EPUB Content Document with which it is associated, as stated in Structure.
It MUST be valid to the Media Overlays schema as defined in Appendix A, Media Overlays Schema and conform to all content conformance constraints expressed in Media Overlay Document Definition.
It MUST meet the conformance constraints for XML documents defined in XML Conformance [EPUB32].
Including in the Manifest
If an EPUB Content Document is wholly or partially referenced by a Media Overlay, then its manifest item element [Packages32] MUST include a media-overlay attribute. The attribute MUST reference the ID [XML] of the manifest item for the corresponding Media Overlay Document. The media-overlay attribute MUST NOT be attached to manifest item elements that do not reference EPUB Content Documents. Manifest items for Media Overlay Documents MUST have the media type application/smil+xml.
Style Information
Visual rendering information for the currently-playing EPUB Content Document element MAY be expressed in the CSS Style Sheet using author-defined classes. These author-defined class names SHOULD be declared in the Package Document metadata using the metadata properties active-class and playback-active-class. The class names are then discoverable by Reading Systems. The active-class and playback-active-class properties MUST NOT be used in conjunction with a refines attribute [Packages32], as they are always considered to apply to the entire Rendition.
When pre-recorded narration is available for a Rendition of an EPUB Publication, Media Overlays provide the ability to synchronize that audio with the text of a Content Document (see also Aural Renditions and Media Overlays).
Text-To-Speech
Inline SSML Phonemes
The incorporation of SSML phonemes functionality [SSML] directly into a EPUB Content Document enables fine-grained pronunciation control, taking precedence over default pronunciation rules and/or referenced pronunciation lexicons (as provided by the PLS format mentioned above). Refer to SSML Attributes [ContentDocs32] for more information.
Pronunciation Lexicons
The inclusion of generic pronunciation lexicons using the W3C PLS format [PRONUNCIATION-LEXICON] enables Authors to provide pronunciation rules that apply to the entire EPUB Publication.
audio
video
General
An EPUB Content Document MUST NOT be referenced by more than one Media Overlay Document.
XHTML or SVG documents that describe the readable content and reference associated media resources (e.g. images, audio and video clips)
Content presentation should adapt to the user preferences
Designed to maximize accessibility for the visually impaired, and Reading Systems typically perform text line layout and pagination on the fly, adapting to the size of the display area, the user's preferred font size, and other environmental factors
Also supports embedded fonts
*Navigation Document (nav)
There are three types of EPUB nav elements. Specify which one is being used through the epub:type attribute
OTHER types are OK also.
hidden
*epub:type
1 of these REQUIRED
toc

page-list
Identifies the nav element that contains a list of pages for a print or other statically-paginated source for the EPUB Publication.
landmarks
Identifies the nav element that contains a list of points of interest.
CONTENT MODEL:
HTML Heading Content
e.g. h1, h2, ....
*ol
The ol child of the nav element represents the primary level of content navigation.
*li
*span or a
A span element MUST be followed by an ol ordered list; it cannot be used in "leaf" li elements.
An a element MAY be followed by an ol ordered list representing a subsidiary content level below that heading (e.g., all the subsection headings of a section).
MUST Conform to:
It MUST conform to the content conformance constraints specific to EPUB Navigation Documents defined in EPUB Navigation Document Definition.
An XHTML Document (using the HTML nav element) to define human/machine readable navigation information.
General Info
Natively supports embedded grammars (e.g. MathML, SVG, etc)

CONTENT (in this order): 1) metadata 2) manifest 3) spine 4) collection
collection
CONTENT (In this order): 1) metadata [0 or 1] 2) collection [1...N], or collection [0+] link [1+]
collection link
*collection
metadata
*role
Allows grouping of logically-related Publication Resources. Enables the development of specialized content identification, processing and rendering features, such as the ability to define embedded preview content, or assemble an index or dictionary from its constituent XHTML Content Documents.
*spine
*itemref
Each itemref element MUST reference the ID [XML] of a unique item in the manifest via the IDREF [XML] in its idref attribute (i.e., two or more itemref elements cannot reference the same item). Each referenced manifest item MUST be either a) an EPUB Content Document or b) another type of Publication Resource which, regardless of whether it is a Core Media Type Resource or a Foreign Resource, MUST include an EPUB Content Document in its fallback chain.
EMPTY!
linear
no
yes
The linear attribute indicates whether the referenced item contains content that contributes to the primary reading order and has to be read sequentially ("yes") or auxiliary content that enhances or augments the primary content and can be accessed out of sequence ("no"). Examples of auxiliary content include: notes, descriptions and answer keys. An itemref that omits the linear attribute is assumed to have the value "yes".
*idref
page-progression-direction
default
The page-progression-direction attribute sets the global direction in which the content flows.
IS: An ordered sequence of ID references to top-level resources in the manifest from which all other resources in the set can be reached or utilized. The spine defines the default reading order of the given Rendition.
Provides an external declarative means to explicitly specify navigation through a collection of documents
*manifest
CONTENT:
*item
Each item element in the manifest identifies a Publication Resource by the IRI [RFC3987] provided in its href attribute. The IRI MAY be absolute or relative. In the case of relative IRIs, Reading Systems MUST use the IRI of the Package Document as the base when resolving these to absolute IRIs. The resulting absolute IRI MUST be unique within the manifest scope.
Represents a Publication Resource
ATTRIBUTES
*svg
*scripted
*remote-resources
*nav

*id
*fallback
The fallback attribute takes an IDREF [XML] that identifies a fallback for the Publication Resource referenced from the item element. Fallbacks MAY be provided for Core Media Type Resources (e.g., to provide a static alternative to a Scripted Content Document). Fallback requirements for Foreign Resources are defined in Manifest Fallbacks.
Manifest Fallback Chains
Are: A mechanism that defines an ordered list of top-level resources as content equivalents. A reading system can then choose between the resources based on which it is capable of rendering.
Identifies and describes the set of resources that collectively compose the given Rendition

OPTIONS:
xmp
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets. XMP standardizes a data model, a serialization format and core properties for the definition and processing of extensible metadata. It also provides guidelines for embedding XMP information into popular image, video and document file formats, such as JPEG and PDF, without breaking their readability by applications that do not support XMP. Therefore, the non-XMP metadata have to be reconciled with the XMP properties. Although metadata can alternatively be stored in a sidecar file, embedding metadata avoids problems that occur when metadata is stored separately.
onix
The ONIX for Books standard provides a free-to-use format for passing descriptive metadata about books between publishers, data aggregators, book retailers and other interested parties in the publishing industry. Metadata concerning one or more book titles can be stored in a suitably formatted XML file known as an 'ONIX message' ready for dissemination. Whereas other data standards exist for storing the contents of a book - the text, layout and graphics - the ONIX for Books standard holds information about the book, similar to, but more extensive than, the information one would typically find on the cover or title page of a printed book or in a library catalog. The ONIX for Books standard provides a way to communicate information about a book's author, publisher, price, publication date, physical dimensions, synopsis and many other details besides. The standard is quite extensive and most publishers currently provide only a few dozen of the many hundreds of pieces of information that the standard is designed to carry.
*media-type
*href
Linked resources are not Publication Resources and MUST NOT be listed in the manifest. A linked resource MAY be embedded in a Publication Resource that is listed in the manifest, however, in which case it MUST be a Core Media Type Resource [EPUB32] (e.g., an EPUB Content Document could contain a metadata record serialized as [RDFA-CORE] or [JSON-LD]).

OPTIONAL ELEMENTS:
type
The [DC11] type element is used to indicate that the given EPUB Publication is of a specialized type (e.g., annotations or a dictionary packaged in EPUB format). An informative registry of specialized EPUB Publication types for use with this element is maintained in the [TypesRegistry], but Authors MAY use any text string as a value.
subject
When a scheme is identified, a subject code MUST be attached using the term property.
Authors MAY identify the system or scheme the element's value is drawn from using the authority property.
The [DC11] subject element identifies the subject of the EPUB Publication. The value of the element SHOULD be the human-readable heading or label, but MAY be the code value if the subject taxonomy does not provide a separate descriptive label.
source
rights

publisher
format
date
Only one date element is allowed.
The date element MUST only be used to define the publication date of the EPUB Publication. The publication date is not the same as the last modified date (the last time the Rendition was changed). It is RECOMMENDED that the date string conform to [ISO8601], particularly the subset expressed in W3C Date and Time Formats [DateTime], as such strings are both human and machine readable.
description
creator
The [DC11] creator element represents the name of a person, organization, etc. responsible for the creation of the content of the Rendition. The role property can be attached to the element to indicate the function the creator played in the creation of the content.
