Accessibility summary |
<ProductFormFeatureDescription> contains a short explanatory summary of the accessibility of the product, or the URL of a web page comprising such a summary, consistent with the more specific conformance, feature and certification details provided. The summary should note both the accessibility features provided and any potential deficiencies. The summary does not remove the requirement for full structured accessibility data, but should be considered a fall-back option if more structured detail cannot be provided or used. Further detailed information may be provided in an external file using codes 94–96. Only for use in ONIX 3.0 or later |

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 <EpubUsageConstraint>. 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 |

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 |
