Curly brackets were never allowed in namespace URIs according to RFC 3986, and so-called namespace-validating XML parsers have the right to reject them a invalid URIs. libexpat >=2.4.5 has become strcter in that regard due to related security issues; with ET.XML instantiating a namespace-aware parser under the hood, this test has no future in CPython.
