  • HTML5 specifies its own syntax rules authors have to follow. These syntax rules are compatible with the XHTML syntax rules althoug this does not imply that parsing such a document with an HTML parser will give the same result as parsing it with an XML parser.
  • HTML5 defines its own parsing rules (including "error correction") for text/html resources and no longer assumes SGML features are supported.
