What is XML?
  • Tagging language like html except you define the
    tags.
  • Design separate from content. (XSLT to add style)
  • Other programs can strip out the information from
    the XML to use in other places.
  • You can define your DTDs so that users only get
    the part of the information that you want them to
    see.
