ALIASES: Filter.ExtractStyleBlocksScope, FilterParam.ExtractStyleBlocksScope
--DESCRIPTION--

If you would like users to be able to define external stylesheets, but
 only allow them to specify CSS declarations for a specific node and
 prevent them from fiddling with other elements, use this directive.
 It accepts any valid CSS selector, and will prepend this to any
 CSS declaration extracted from the document. For example, if this
 directive is set to <code>#user-content</code> and a user uses the
 selector <code>a:hover</code>, the final selector will be
 <code>#user-content a:hover</code>.


 The comma shorthand may be used; consider the above example, with
 <code>#user-content, #user-content2</code>, the final selector will
 be <code>#user-content a:hover, #user-content2 a:hover</code>.


 Warning: It is possible for users to bypass this measure
 using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
 Purifier, and I am working to get it fixed. Until then, HTML Purifier
 performs a basic check to prevent this.
