From 7da97f61816f3cadaa6788804b22a2434b40e8c5 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 21 Feb 2022 08:16:09 -0800 Subject: [PATCH] bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453) (GH-31472) 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.
