Last Call for Review of Proposed Corrections to EPUB 3.3

 The Publishing Maintenance Working Group has proposed corrections to the W3C Recommendation of EPUB 3.3. EPUB® 3 defines a distribution and interchange format for digital publications and documents. The EPUB format provides a means of representing, packaging, and encoding structured and semantically enhanced web content — including HTML, CSS, SVG, and other resources — for distribution in a single-file container. This specification defines the authoring requirements for EPUB publications and represents the third major revision of the standard.

Proposed corrections are marked in the document. Comments, including implementation experience, are welcome via GitHub through 10 March 2025.
