This directive enables aggressive pre-filter fixes HTML Purifier can
perform in order to ensure that open angled-brackets do not get killed
during parsing stage. Enabling this will result in two preg_replace_callback
calls and at least two preg_replace calls for every HTML document parsed;
if your users make very well-formed HTML, you can set this directive false.
This has no effect when DirectLex is used.
<strong>Notice:</strong> This directive's default turned from false to true
in HTML Purifier 3.2.0.
