“Use W3C technologies when they are available and appropriate for a task and use the latest versions when supported. ”

In other words, do not use proprietary browser technologies unless there is no other solution.

Some current W3C technologies are:

  • MathML for mathematical equations.
  • HTML, XHTML, XML for structured documents.
  • RDF for metadata.
  • SMIL to create multimedia presentations.
  • CSS and XSL to define style sheets.
  • XSLT to create style transformations.
  • PNG for graphics (although some are best expressed in JPG, a non-W3C spec).
