National bodies that are members of ISO or I
5、EC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, gov
6、ernmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
7、Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the nation
8、al bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, the joint technical committee may decide to publish an ISO/IEC Technical Specification (ISO/IEC TS), which represents an agreement between the members of the joint technical
9、committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/IEC TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the
10、ISO/IEC TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC sha

ISO/IEC TS 30135 series were prepared by Korean Agency for Technology and Standards (as KS X 6070 series) with International Digital Publishing Forum and were adopted, under a special “fast-track procedure”, by Joint Technical
12、 Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and IEC.

Acknowledgements and Contributors References 1 Overview 1.1 Purpose and Scope This section is informative This specification, EPUB Content Documents 3.0, defines profiles of HTML5, SVG, and CSS for use in the context of EPUB P
27、ublications. This specification is one of a family of related specifications that compose EPUB 3, the third major revision of an interchange and delivery format for digital publications based on XML and Web Standards. It is meant to be read and understood in concert with the other specifications tha
28、t make up EPUB 3: The EPUB 3 Overview EPUB3Overview, which provides an informative overview of EPUB and a roadmap to the rest of the EPUB 3 documents. The Overview should be read first. EPUB Publications 3.0 Publications30, which defines publication-level semantics and overarching conformance requir
29、ements for EPUB Publications. EPUB Open Container Format (OCF) 3.0 OCF3, which defines a file format and processing model for encapsulating a set of related resources into a single-file (ZIP) EPUB Container. EPUB Media Overlays 3.0 MediaOverlays30, which defines a format and a processing model for s
30、ynchronization of text and audio. This specification supersedes Open Publication Structure (OPS) 2.0.1 OPS2. Refer to EPUB3Changes for information on differences between this specification and its predecessor. 1.2 Relationship to Other Specifications This section is informative 1.2.1 Relationship to
31、 HTML5 The XHTML document type defined by this specification is based on W3C HTML5, and inherits all definitions of semantics, structure and processing behaviors from the HTML5 specification unless otherwise specified. In addition, this specification defines a set of extensions to the W3C HTML5 docu
32、ment model that Authors may include in XHTML Content Documents. This specification defines a simplified processing model that does not require Reading Systems to support scripting, HTML5 forms or the HTML5 DOM. EPUB Reading Systems conformant with this specification are only required to be able to p
33、rocess a conforming EPUB Content Document. As support for scripting and HTML5 forms are optional Reading System features, a conformant Reading System might not be a fully-conformant HTML5 User Agent (i.e., it might not implement the complete HTML5 processing model). 1.2.2 Relationship to S VG This s
34、pecification defines a restricted subset of SVG 1.1 to represent vector graphics inline in XHTML Content Documents and as standalone SVG Content Documents. 1.2.3 Relationship to CS S The CSS profile defined in this specification has CSS 2.1 CSS2.1 as its baseline. Any CSS Style Sheet that conforms t
35、o CSS 2.1 may be used in the context of an EPUB Publication, except as noted in CSS 2.1. This specification also incorporates features defined by CSS3 Modules and introduces EPUB-specific CSS constructs. 1.2.4 EPUB 3 Versioning S trategy EPUB 3 references W3C specifications that are not yet final, a
36、nd incompatible changes to them may occur in the future that would cause EPUB 3 Content Documents that were previously conformant to no longer be conformant to the latest versions of the referenced specifications. The IDPF anticipates revising the EPUB 3 specifications if and when such incompatible
37、changes occur, updating the normative constraints defined herein as necessary and incrementing the minor version number of EPUB 3 (e.g., publishing an EPUB 3.0.n ). 1.3 Terminology EPUB Publication (or Publication) A logical document entity consisting of a set of interrelated resources and packaged
38、in an EPUB Container, as defined by this specification and its sibling specifications. Publication Resource A resource that contains content or instructions that contribute to the logic and rendering of the EPUB Publication. In the absence of this resource, the Publication might not render as intend
39、ed by the Author. Examples of Publication Resources include the Package Document, EPUB Content Documents, EPUB Style Sheets, audio, video, images, embedded fonts and scripts. With the exception of the Package Document itself, Publication Resources must be listed in the manifest Publications30 and mu
40、st be bundled in the EPUB container file unless specified otherwise in Publication Resource Locations Publications30.Examples of resources that are not Publication Resources include those identified by the Package Document link Publications30 element and those identified in outbound hyperlinks that
41、resolve outside the EPUB Container (e.g., referenced from an HTML5 a element href attribute). Core Media Type Resource A Publication Resource that is a Core Media Type and may therefore be included in the EPUB Publication without the provision of fallbacks Publications30. EPUB Content Document A Pub
42、lication Resource that conforms to one of the EPUB Content Document definitions (XHTML or SVG). An EPUB Content Document is a Core Media Type, and may therefore be included in the EPUB Publication without the provision of fallbacks Publications30. XHTML Content Document An EPUB Content Document conf
43、orming to the profile of HTML5 defined in XHTML Content Documents. XHTML Content Documents use the XHTML syntax of HTML5. SVG Content Document An EPUB Content Document conforming to the constraints expressed in SVG Content Documents. EPUB Navigation Document A specialization of the XHTML Content Doc
44、ument, containing human- and machine-readable global navigation information, conforming to the constraints expressed in EPUB Navigation Documents. Scripted Content Document An EPUB Content Document that includes scripting or an XHTML Content Document that contains HTML5 forms elements. Refer to Scri
45、pted Content Documents for more information. Top-level Content Document An EPUB Content Document referenced directly from the spine Core Media Type A set of Publication Resource types for which no fallback is required. Refer to Publication Resources Publications30 for more information. Package Docum
46、ent A Publication Resource carrying bibliographical and structural metadata about the EPUB Publication, as defined in Package Documents Publications30. Manifest A list of all Publication Resources that constitute the EPUB Publication. Refer to manifest Publications30 for more information. Spine An o
47、rdered list of Publication Resources, typically EPUB Content Documents, representing the default reading order of the Publication. Refer to spine Publications30 for more information. Text-to-Speech (TTS) The rendering of the textual content of an EPUB Publication as artificial human speech using a s
48、ynthesized voice. EPUB Style Sheet (or Style Sheet) A CSS Style Sheet conforming to the CSS profile defined in EPUB Style Sheets. Viewport The region of an EPUB Reading System in which the content of an EPUB Publication is rendered visually to a User. CSS Viewport A Viewport capable of displaying CS
49、S-styled content. SVG Viewport A Viewport capable of displaying SVG images. EPUB Container (or Container) The ZIP-based packaging and distribution format for EPUB Publications defined in OCF3. Author The person(s) or organization responsible for the creation of an EPUB Publication, which is not necessarily the creator of the content and resources it contains. User An individual that consumes an EPUB Publication using an EPUB Reading System. EPUB Reading System (or Reading System) A syst
