Valid Documents Document types support Below is a list of sample documents for a number of document types the validator is supposed to be supporting. The first validate link will attempt validation with the current instance, for test purposes.

(also test for Bug 5031) Valid Doctypeless Documents Some document types (SVG) do not require the presence of the DOCTYPE declaration, although a DTD can be used to validate. The validator can however determine the version to validate against by preparsing the root element and the presence of version, baseProfile attributes. (control) test for validation of SVG 1.0 with Doctype http://qa-dev.w3.org/wmvs/HEAD/dev/tests/3663-svg-10-doctype.svg Pass Valid SVG 1.0, using a DOCTYPE Test for validation of Doctype-less SVG 1.0 http://qa-dev.w3.org/wmvs/HEAD/dev/tests/3663-svg-10-doctypeless.svg Pass Valid SVG 1.0, but no declared DOCTYPE.

The validator may use a default. Valid Documents, with Warnings Test document with reference to a non-existing ID http://qa-dev.w3.org/wmvs/HEAD/dev/tests/2342-opensp_type_X.html Pass yes Reference to a non-existing ID (opensp message type X, See bug 2342). Test for warnings about non-SGML character(s) http://qa-dev.w3.org/wmvs/HEAD/dev/tests/nonSGML-chars.html Pass Non-SGML Chars Test for warning about ampersand as data (in SGML) http://qa-dev.w3.org/wmvs/HEAD/dev/tests/ampersand-as-data_html401.html Pass yes HTML 4.01 Document with Ampersand as data

Valid XHTML 1.0 documents not conforming to HTML compatibility Guidelines The XHTML 1.0 spec states: XHTML Documents which follow the guidelines set forth in Appendix C, "HTML Compatibility Guidelines" may be labeled with the Internet Media Type "text/html" [RFC2854], as they are compatible with most HTML browsers. . It's really unclear as to whether this is a real conformance issue, but regardless there is demand for sending at least warnings when a text/html XHTML 1.0 document does not follow these guidelines. Test of warning for non-HTML compatible XHTML document (C1) http://qa-dev.w3.org/wmvs/HEAD/dev/tests/xhtml1-appc-xmldecl.html Pass yes C1: XML Declaration Test of warning for non-HTML compatible XHTML document (C2) http://qa-dev.w3.org/wmvs/HEAD/dev/tests/xhtml1-appc-empty.html Pass yes C2: empty elements and minimized form Test of warning for non-HTML compatible XHTML document (C3) http://qa-dev.w3.org/wmvs/HEAD/dev/tests/xhtml1-appc-emptycontent.html Pass yes C3: Element Minimization and Empty Element Content Valid Documents served with a wrong media type Test of warning for HTML 4.01 served with wrong media type http://qa-dev.w3.org/wmvs/HEAD/dev/tests/html401-strict.xhtml Fail yes HTML 4.01 Strict served with an XHTML mime type.

This may pass validation with a warning as text/html will not trigger an unambiguous parsing mode, and doctype will prevail. (is that wrong?) Test of warning for MathML served with wrong media type http://qa-dev.w3.org/wmvs/HEAD/dev/tests/mathml2.html yes MathML 2.0 as text/html This may pass validation with a warning as text/html will not trigger an unambiguous parsing mode, and doctype will prevail.
