The first such concrete syntax is "HTML5". This is the format recommended for most authors. It is compatible with all legacy Web browsers. If a document is transmitted with the MIME type text/html, then it will be processed as an "HTML5" document by Web browsers.
The second concrete syntax uses XML, and is known as "XHTML5". When a document is transmitted with an XML MIME type, such as application/xhtml+xml, then it is processed by an XML processor by Web browsers, and treated as an "XHTML5" document. The last sentence is awkward. I think making it more parallel with the previous paragraph would help. I.e. If a document is transmitted with an XML MIME type, such as application/xhtml+xml, then it will be processed as an "XHTML5" document by Web browsers. -- Elliotte Rusty Harold [email protected]
