EPUB 3 - MathML with the mathml Property Declared
An EPUB 3 with a block MathML equation and the required properties="mathml" on its content document. The baseline for MathML support, paired with a twin that omits the declaration.

Testing contract
Expected to pass- Scenario
- Open the chapter in a reader and inspect the equation.
- Expected result
- The fraction, radical and superscript are laid out as mathematics, and the manifest property lets a reader decide up front whether it can render the document.
What is a .epub file?
EPUB is the open e-book standard, a ZIP archive containing XHTML content documents, CSS, images, and a package manifest describing reading order and metadata. It supports reflowable text that adapts to screen size and is supported by most e-readers except Kindle natively. It is the dominant format for distributable e-books.
How to use this file
Use an example EPUB to test e-book parsing, ZIP-package and manifest handling, reading-order and metadata extraction, and rendering in e-reader applications.
How to use this file for testing
“EPUB 3 - MathML with the mathml Property Declared” is a deterministic Novus Examples fixture for Conversion testing, HTML parsing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
E-book fixtures are structured archives documented down to their spine and manifest. Test readers and converters, and where a valid↔intentionally-invalid pair exists, assert graceful handling of the malformed container.

- epubEPUB 3 - Inline SVG in XHTML (svg property)SVG written straight into an XHTML content document, with properties="svg" declared on the manifest item as EPUB 3 requires. The other half of the SVG question: inline vector markup rather than a standalone content document.
- epubEPUB 3 - Scripted Content with the scripted PropertyAn EPUB 3 whose one content document declares properties="scripted" and contains a single inline script that rewrites one paragraph. It makes no network request and reads correctly with scripting switched off, so it tests the property and the fallback rather than the script.
- epubEPUB 3 - SVG Content Document in the SpineAn EPUB 3 whose first spine item is an SVG content document rather than XHTML, followed by a chapter that explains what should have appeared. For testing readers that assume every reading-order document is XHTML.
- epubEPUB 3 - SVG Cover Wrapping a Raster ImageA fixed-layout cover built as an SVG content document that pulls in a PNG through xlink:href and centres it as a single-page spread. For testing cover extraction, which usually looks for a raster and finds vector markup instead.
