FilterParam.ExtractStyleBlocksTidyImpl TYPE: mixed/null VERSION: 3.1.0 DEFAULT: NULL --DESCRIPTION--
If left NULL, HTML Purifier will attempt to instantiate a csstidy
class to use for internal cleaning. This will usually be good enough.
However, for trusted user input, you can set this to false
to
disable cleaning. In addition, you can supply your own concrete implementation
of Tidy's interface to use, although I don't know why you'd want to do that.
