--DESCRIPTION--

<p>
    If HTML Purifier's style attributes set is unsatisfactory for your needs, 
    you can overload it with your own list of tags to allow.  Note that this 
    method is subtractive: it does its job by taking away from HTML Purifier 
    usual feature set, so you cannot add an attribute that HTML Purifier never 
    supported in the first place.

    <strong>Warning:</strong> If another directive conflicts with the 
    elements here, <em>that</em> directive will win and override.
