XML Syntax Rules

•       All XML Elements Must Have a Closing Tag

–      In HTML, some elements do not have to have a closing tag:

<b><i>This text is bold and italic</i></b> [Proper]

•       XML Documents Must Have a Root Element

•       <root>
  <child>
    <subchild>.....</subchild>
  </child>
</root>

•       XML Attribute Values Must be Quoted
