• All element and attribute names must be lower case.
• End tags are required for all elements, either: <tag>...</tag> or <empty />.
• All attribute values must be (single or double) quoted.
• All paired elements must be nested properly, i.e. the following is an error:
     <i>fee<b>foo</i>fie</b>
  should be:
