-/**
- * 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.
