This is a major schema update, to reuse the latest schemas from the Nu Html Checker, with the following tweaks: - adapt the integration in schema drivers - replace the Nu Html Checker's pluggable datatype library with EPUBCheck’s more limited static RelaxNG datatypes - add EPUB-specific content model extensions Changes specific to XHTML: - keep allowing missing `title` in the `head` element - but report missing `title` as a WARNING (with a Schematron check) - keep allowing `meta http-equiv` in encoding declaration state (allowed in W3C but forbidden in WHATWG's HTML standard) - keep allowing the `border` attribute on `table` elements (allowed in W3C but forbidden in WHATWG's HTML standard) - report `aria-describedat` as a schema error - add tests for several obsolete features which appeared in previous test content (`time/@pubdate`, `iframe/@seamless`, `keygen`, `menu`, `dropzone`, `contextmenu`, in-body `style`, `style/@scoped`) Changes specific to MathML: - use the schemas from Nu Html Checker, which are based on older MathML schema but bring some specific tweaks. - re-add the changes from the newer MathML 3.0 (2nd edition) schemas - improve the schema checks of EPUB-specific `annotation-xml` restrictions (notably check the combination of the `name` and `encoding` attributes) Changes specific to SVG: - use the schemas from Nu Html Checker, which are based SVG 1.1 Changes specific to Navigation Documents: - do not check the presence of mandatory headings on `nav` elements with no `epub:type` attribute Fixes #892 Fixes #779 Fixes #896 Fixes (partially?) #893 Closes #448

The Content Documents specification now uses an auto-updating reference to the latest W3C version of HTML so that changes can be immediately reflected in validation. Currently this is HTML 5.2.
