+Subject: [PATCH] bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453)
+ (GH-31471)
+
+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.
+
+References:
+- https://datatracker.ietf.org/doc/html/rfc3968
+- https://www.w3.org/TR/xml-names/
+
+Also, test_minidom.py: Support Expat >=2.4.5
+(cherry picked from commit 2cae93832f46b245847bdc252456ddf7742ef45e)
