    A PCRE regular expression that will be matched against an iframe URI.  This is
    a relatively inflexible scheme, but works well enough for the most common
    use-case of iframes: embedded video.  This directive only has an effect if
    %HTML.SafeIframe is enabled.  Here are some example values:
    <li><code>%^</code> - Allow YouTube videos</li>
    <li><code>%^</code> - Allow Vimeo videos</li>
    <li><code>%^http://(|</code> - Allow both</li>
    Note that this directive does not give you enough granularity to, say, disable
    all <code>autoplay</code> videos.  Pipe up on the HTML Purifier forums if this
    is a capability you want.
