A well-formed document must conform to the following rules, among others:
1. Non-empty elements are delimited by both a start-tag and an end-tag.
2. Empty elements may be marked with an empty-element (self-closing) tag, such as <IAmEmpty />. This is equal to <IAmEmpty></IAmEmpty>.
3. All attribute values are quoted with either single (') or double (") quotes. Single quotes close a single quote and double quotes close a double quote.
4. Tags may be nested but must not overlap. Each non-root element must be completely contained in another element.

6. Element names are case-sensitive. For example, the following is a well-formed matching pair:
