Core.DisableExcludes TYPE: bool DEFAULT: false VERSION: 4.5.0 --DESCRIPTION--
  This directive disables SGML-style exclusions, e.g. the exclusion of
  <object> in any descendant of a
  <pre> tag.  Disabling excludes will allow some
  invalid documents to pass through HTML Purifier, but HTML Purifier
  will also be less likely to accidentally remove large documents during
  processing.
