 * <a href="#HTMLElement">elements</a>.
 * <p>
 * An <i><a name="HTMLElement">HTML element</a></i> is a <a href="Element.html#Normal">normal element</a> with a
 * {@linkplain Element#getName() name} that matches one of the {@linkplain HTMLElementName HTML element names} (ignoring case).
 * This type of element spans the logical HTML element as described in the
 * <a target="_blank" href="http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.1">HTML 4.01 specification section 3.2.1</a>,
 * which may be <a href="Element.html#ImplicitlyTerminated">implicitly terminated</a> if it specifies an
 * {@linkplain #getEndTagOptionalElementNames() optional end tag}.
 * <p>
 * The term <i><a name="NonHTMLElement">Non-HTML element</a></i> refers to a <a href="Element.html#Normal">normal element</a>
 * with a {@linkplain Element#getName() name} that does not match one of the {@linkplain HTMLElementName HTML element names}.
 * This type of element must be either a <a href="Element.html#SingleTag">single tag element</a> or
 * <a href="Element.html#ExplicitlyTerminated">explicitly terminated</a>.
 * <p>
 * All of the sets returned by the methods in this class may be modified to customise the behaviour of the parser.
 * Care must be taken however to ensure that the sets only contain tag names in lower case.
 * <p>
 * Below is a table summarising the default characteristics of each <a href="#HTMLElement">HTML element</a>.  See also the
 * <a target="_blank" href="http://www.w3.org/TR/html401/index/elements.html">index of elements in the HTML 4.01 specification</a>
 * for the official table containing similar information.
