Any @namespace rules must follow all @charset and @import rules and precede all other non-ignored at-rules and rule sets in a style sheet. According to IETC WebKit is the only engin which gets this wrong (is too lenient on when you can use @namespace): http://samples.msdn.microsoft.com/ietestcenter/css3/namespaces/syntax-021.xml I'm not sure how much this matters in practice.

Safari Technology Preview 152 pass all these test cases now: https://wpt.fyi/results/css/css-namespaces?label=master&label=experimental&aligned&view=subtest&q=css%20namespace I am going to mark this as "RESOLVED CONFIGURATION CHANGED". Thanks!

We have ietestcenter/css3/namespaces/syntax-021.xml in the WebKit repository, and it passes.
