XHTML

• Reformulation of HTML 4.01 as an XML Application
  • Better integration with other, XML based specs
  • (MathML, SMIL, SVG, etc)
  • Final separation of style and content
  • Better, more robust implementations
  • Usage of XML tools to manage (X)HTML content (eg, XSLT)
• Why doing it (ie, why not rely on XML only)?
  • HTML has a large and useful set of semantics
  • The tags are already known
  • Why reinvent the wheel?
