/**
 * Definition of the purified HTML that describes allowed children,
 * attributes, and many other things.
 *
 * Conventions:
 *
 * All member variables that are prefixed with info
 * (including the main $info array) are used by HTML Purifier internals
 * and should not be directly edited when customizing the HTMLDefinition.
 * They can usually be set via configuration directives or custom
 * modules.
 *
 * On the other hand, member variables without the info prefix are used
 * internally by the HTMLDefinition and MUST NOT be used by other HTML
 * Purifier internals. Many of them, however, are public, and may be
 * edited by userspace code to tweak the behavior of HTMLDefinition.
 *
 * @note This class is inspected by Printer_HTMLDefinition; please
 *       update that class if things here change.
 *
 * @warning Directives that change this object's structure must be in
 *          the HTML or Attr namespace!
