- A document that uses polyglot markup is a document that is a stream of bytes that parses into identical document trees
- (with some exceptions, as noted in the <a href="#introduction">Introduction</a>) when processed as HTML and when processed as XML.
- Polyglot markup that meets a well-defined set of constraints is interpreted as compatible, regardless of whether they are processed as HTML or as XHTML, per the HTML5 specification.
- Polyglot markup uses a specific DOCTYPE, namespace declarations, and a specific case—normally lower case but occasionally camel case—for element and attribute names.
- Polyglot markup uses lower case for certain attribute values.
- Further constraints include those on void elements, named entity references, and the use of scripts and style.

- <p>
- It is often valuable to be able to serve HTML5 documents that are also well formed XML documents.
- An author may, for example, use XML tools to generate a document, and they and others may process the document using XML tools.
- The language used to create documents that can be parsed by both HTML and XML parsers is called <dfn id="dfn-polyglot-markup">polyglot markup</dfn>.
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> is the overlap language of documents that are both HTML5 documents and XML documents.
- It is recommended that these documents be served as either <code>text/html</code> (if the content is transmitted to an HTML-aware user agent)
- or <code>application/xhtml+xml</code> (if the content is transmitted to an XHTML-aware user agent).
- Other permissible MIME types are <code>text/xml</code>, <code>application/xml</code>,
- and any MIME type whose subtype ends with the four characters "<code>+xml</code>". [<cite><a class="bibref" href="#bib-XML-MT">XML-MT</a></cite>]
- </p>
- <p>
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> results in:
- </p>
- <ul>
- <li>a valid HTML document. [<cite><a class="bibref" href="#bib-HTML5">HTML5</a></cite>]</li>
- <li>a <a href="http://www.w3.org/TR/2008/PER-xml-20080205/#sec-well-formed">well-formed XML</a> document. [<cite><a class="bibref" href="#bib-XML10">XML10</a></cite>]</li>
- <li>identical DOMs when processed as HTML and when processed as XML.
- A noteable exception to this is that HTML and XML parsers generate different DOMs for some
- <code>xml</code> (<code>xml:lang</code>, <code>xml:space</code>, and <code>xml:base</code>),
- <code>xmlns</code> (<code>xmlns=""</code> and <code>xmlns:xlink=""</code>), and <code>xlink</code> (such as <code>xlink:href</code>) attributes.
- XML requires and HTML5 permits these attributes in certain locations and the attributes are preserved by HTML parsers.
- </li>
- </ul>
- <p>
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> is not constrained:
- </p>
- <ul>
- <li>to be <a href="http://www.w3.org/TR/2008/PER-xml-20080205/#dt-valid">valid XML</a>. [<cite><a class="bibref" href="#bib-XML10">XML10</a></cite>]</li>
- <li>by conformance to any XML DTD.</li>
- </ul>
- <p>
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> is scripted according to the rules of XML (does not use <code>document.write</code>, for example)
- and excludes HTML elements that are impossible to replicate in an XML parser (does not use the <code>noscript</code> element, for example).
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> triggers non-quirks mode in HTML parsers,
- as non-quirks mode is closest to XML-mode rendering, in regard to both DOM and CSS.
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> results in the same encoding and the same language in both HTML-mode and XML-mode.
- </p>
- <p>
- All web content need not be authored in <a href="#dfn-polyglot-markup" class="internalDFN">polyglot markup</a>.
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> is ideal for publishing when there's a strong desire to serve both HTML and XML tool chains
- without simultaneously having to maintain dual copies of the content: one in HTML and a second in XHTML.
- In addition, a single <a href="#dfn-polyglot-markup" class="internalDFN">polyglot markup</a> output requires less infrastructure to produce than to produce both HTML and XHTML output for the same content.
- <a title="polyglot markup" href="#dfn-polyglot-markup" class="internalDFN">Polyglot markup</a> is also be beneficial when lightweight processes—such as
- quick testing or even hand-authoring—are applied to content intended to be published both as HTML and XHTML,
- especially if that content is not sent through a tool chain.
