URI.DefaultScheme
TYPE: string/null
DEFAULT: 'http'
--DESCRIPTION--

<p>
    Defines through what scheme the output will be served, in order to
    select the proper object validator when no scheme information is present.
</p>

<p>
    Starting with HTML Purifier 4.9.0, the default scheme can be null, in
    which case we reject all URIs which do not have explicit schemes.
