Simplification via DTD

XML can be simplifed by:

• Defaulting role, type, etc, attributes to tag name
• Defaulting type appropriately

With an appropriate DTD, the example could be reduced to, eg:

  <ABC
    xlink:href    = "http://www.w3.org/"
    xlink:role    = "w3chome"
    xlink:title   = "W3C Home Page"
  The W3C
  </ABC>
