+URI.Base
+TYPE: string/null
+VERSION: 2.1.0
+DEFAULT: NULL
+--DESCRIPTION--
+
+<p>
+    The base URI is the URI of the document this purified HTML will be
+    inserted into.  This information is important if HTML Purifier needs
+    to calculate absolute URIs from relative URIs, such as when %URI.MakeAbsolute
+    is on.  You may use a non-absolute URI for this value, but behavior
+    may vary (%URI.MakeAbsolute deals nicely with both absolute and
+    relative paths, but forwards-compatibility is not guaranteed).
+    <strong>Warning:</strong> If set, the scheme on this URI
+    overrides the one specified by %URI.DefaultScheme.
