------- Additional Comments from Daniel Glazman <daniel at glazman.org>
Per CSS 3 Namespaces spec [1], @namespace rules must follow all @charset and
@import rules. This is not enforced at this time by CSSParser, and that's one
of the last tests from the Namespaces Test Suite WebKit fails [2].

I have written a patch to fix this bug. Please excuse me in advance if it does
not strictly follow WebKit coding style rules or misses an important
architectural step: this is my very first patch in WebKit...
