W3C EPUBCheck — BSD 3-Clause License The following material is taken from, or derived from, the Java EPUBCheck project: - **RELAX NG schemas** bundled in `schemas/` and embedded (gzipped) in the published bundle: `container.rng`, `datatypes.rng`, `epub-mathml3-inc.rng`, `epub-nav-30.rnc`, `epub-nav-30.rng`, `epub-prefix-attr.rng`, `epub-shared-inc.rng`, `epub-ssml-attrs.rng`, `epub-svg-30.rnc`, `epub-svg-30.rng`, `epub-svg-forgiving-inc.rng`, `epub-switch.rng`, `epub-trigger.rng`, `epub-type-attr.rng`, `epub-xhtml-30.rnc`, `epub-xhtml-30.rng`, `epub-xhtml-inc.rng`, `epub-xhtml-integration.rng`, `epub-xhtml-svg-mathml.rng`, `ncx.rng`, `ocf-container-30.rnc`, `ocf-container-30.rng`, `opf.rng`, `opf20.rng`, `package-30.rnc`, `package-30.rng`. Most are converted from EPUBCheck's RELAX NG compact (`.rnc`) sources and have their `` directives inlined. A few carry small local edits — `opf20.rng`, for one, gains a `` element so it can be used as a standalone grammar — but the grammars themselves are unchanged. - **The message catalogue** in `src/messages/messages.ts`: message identifiers (`RSC-005`, `OPF-014`, …), their default severities and their wording follow EPUBCheck's `MessageBundle.properties`, so that both tools report the same problem under the same name. - **Test fixtures and test scenarios** under `test/` are ported from EPUBCheck's test suite and test EPUBs. These are not part of the published package. ``` Copyright © 2007 Adobe Systems Incorporated Copyright © 2008 IDPF Copyright © 2017 W3C (MIT, ERCIM, Keio, Beihang) Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 1.

RELAX NG Schema for (X)HTML 5 — MIT License (the Nu Html Checker) These modules reach this project through EPUBCheck, which bundles them as the basis of its EPUB 3 XHTML Content Document grammar. The following files in `schemas/` are converted from those `.rnc` sources: `applications.rng`, `aria.rng`, `block.rng`, `common.rng`, `core-scripting.rng`, `data.rng`, `embed.rng`, `form-datatypes.rng`, `media.rng`, `meta.rng`, `microdata.rng`, `phrase.rng`, `rdfa.rng`, `revision.rng`, `ruby.rng`, `sectional.rng`, `structural.rng`, `tables.rng`, `web-components.rng`, `web-forms.rng`, `web-forms2.rng`. Their content is also inlined into the generated `epub-xhtml-30.rng` and `epub-nav-30.rng`. ``` Copyright (c) 2005-2007 Elika J.

MathML 3 and SVG 1.1 schemas — W3C Software Notice and License The MathML 3 modules — `mathml3-common.rng`, `mathml3-content.rng`, `mathml3-inc.rng`, `mathml3-presentation.rng`, `mathml3-strict-content.rng` — and the SVG 1.1 modules inlined into `epub-svg-30.rng` and `epub-xhtml-30.rng` are used and distributed under the W3C Software Notice and License.
