displayTransformability #7

Description

@madeleinerothberg

I was asked to write some language to clarify that the Schema.org property displayTransformability is equivalent to the concept of reflow capability and provides broad-based accessibility in most ebooks. I'm not sure where this section should go in the document. Note that displayTransformability could be considered part of Screen Reader Friendly, which is currently written to only account for accessModeSufficient=text. This would allow Screen Reader Friendly on books that do not have image descriptions but do have readable text, which is an issue to consider before adding this new text as drafted.

EPUB accessibility metadata includes the important property displayTransformability, which is sometimes called reflow capability. Text that can be transformed into different kinds of displays can meet the needs of a wide range of readers by providing the text in synthesized speech, large print, alternate colors, braille, or any other presentation. Nearly all ebooks provide displayTransformability. Exceptions include picture books or other visually-presented text, where the text is part of an image, and fixed-format large print books, which are intended to meet the need for large print but do not have transformable text. Audio books, which have no true text, would also lack displayTransformability. Any ebook that offers displayTransformability is largely accessible to many users and could qualify as Screen Reader Friendly.
