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

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

    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.
