 * Tags are used to delimit the start and end of elements in the markup.
 * Raw text, escapable raw text, and normal elements have a start tag to indicate where they begin,
 * and an end tag to indicate where they end.
 * The start and end tags of certain normal elements can be omitted,
 * as described below in the section on [[#optional tags]]. Those that cannot be omitted must not be omitted.
 * Void elements only have a start tag; end tags must not be specified for void elements.
 * Foreign elements must either have a start tag and an end tag, or a start tag that is marked as self-closing,
 * in which case they must not have an end tag.
