Single logical reading order - All or substantially all textual matter is arranged in a single logical reading order (including text that is visually presented as separate from the main text flow, eg in boxouts, captions, tables, footnotes, endnotes, citations, etc). Non-textual content is also linked from within this logical reading order. (Purely decorative non-text content can be ignored). All or substantially all audio content should also have a single logical ‘reading order’, which is the order the content should be presented to the listener

No reading system accessibility options actively disabled (except) - No accessibility features or content rendering options offered by the reading system, device or reading software (including but not limited to the ability to modify or choose text size or typeface, word and line spacing, zoom level, text or background color, or use of text-to-speech) are limited, disabled, overridden or otherwise unusable with the product EXCEPT – in ONIX 3 messages only – those specifically noted as subject to restriction or prohibition in . Note that provision of any significant part of the textual content as images (ie as pictures of text, rather than as ‘text-as-text’, and without any textual equivalent) or the application of some technical protection measures (DRM), inevitably prevents full use of these accessibility options. Code 10 means ‘this e-publication is accessible to the full extent that the file format and types of content allow, on a specific reading device, by default, without necessarily inluding any additions such as textual descriptions of images or enhanced navigation. Note that for reflowable e-books, this means code 36 also applies, although code 10 can also be used with accessible non-reflowable (fixed-format) e-publications and with audio material. Should be used with other codes that describe any additions to enhance the level of accessibility

Table of contents navigation - Table of contents allows direct (eg hyperlinked) access to all levels of text organization above individual paragraphs (ie to all chapters, sections and subsections that exist within the text), and to all tables, figures, illustrations etc (non-textual items such as illustrations, tables, audio or video content may be directly accessible from the Table of contents, or from a similar List of illustrations, List of tables, etc)
