+/**
+ * Chainable filters for custom URI processing.
+ *
+ * These filters can perform custom actions on a URI filter object,
+ * including transformation or blacklisting.  A filter named Foo
+ * must have a corresponding configuration directive %URI.Foo,
+ * unless always_load is specified to be true.
+ *
+ * The following contexts may be available while URIFilters are being
+ * processed:
+ *
+ *      - EmbeddedURI: true if URI is an embedded resource that will
+ *        be loaded automatically on page load
+ *      - CurrentToken: a reference to the token that is currently
+ *        being processed
+ *      - CurrentAttr: the name of the attribute that is currently being
+ *        processed
+ *      - CurrentCSSProperty: the name of the CSS property that is
+ *        currently being processed (if applicable)
+ *
+ * @warning This filter is called before scheme object validation occurs.
+ *          Make sure, if you require a specific scheme object, you
+ *          you check that it exists. This allows filters to convert
+ *          proprietary URI schemes into regular ones.
