d4a05a |
Support expat 2.4.5
|
|
|
d4a05a |
|
|
|
d4a05a |
Curly brackets were never allowed in namespace URIs
|
|
|
d4a05a |
according to RFC 3986, and so-called namespace-validating
|
|
|
d4a05a |
XML parsers have the right to reject them a invalid URIs.
|
|
|
d4a05a |
|
|
|
d4a05a |
libexpat >=2.4.5 has become strcter in that regard due to
|
|
|
d4a05a |
related security issues; with ET.XML instantiating a
|
|
|
d4a05a |
namespace-aware parser under the hood, this test has no
|
|
|
d4a05a |
future in CPython.
