HTML.AllowedAttributes
TYPE: lookup/null
VERSION: 1.3.0
DEFAULT: NULL
--DESCRIPTION--

<p>
    If HTML Purifier's attribute set is unsatisfactory, overload it! 
    The syntax is "tag.attr" or "*.attr" for the global attributes 
    (style, id, class, dir, lang, xml:lang).
</p>
<p>
    <strong>Warning:</strong> If another directive conflicts with the 
    elements here, <em>that</em> directive will win and override. For 
    example, %HTML.EnableAttrID will take precedence over *.id in this 
    directive.  You must set that directive to true before you can use 
    IDs at all.
