-/**
- * Validates a URI in CSS syntax, which uses url('http://example.com')
- * @note While theoretically speaking a URI in a CSS document could
- *       be non-embedded, as of CSS2 there is no such usage so we're
- *       generalizing it. This may need to be changed in the future.
- * @warning Since HTMLPurifier_AttrDef_CSS blindly uses semicolons as
- *          the separator, you cannot put a literal semicolon in
- *          in the URI. Try percent encoding it, in that case.
