416106 - author specified identifiers are now case-sensitive

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Anne (:annevk)]

CSS author specifiied identifiers, such as CSS namespace prefixes, are now case-sensitive.

@namespace foo "x";
FOO|x { background:red }

will not match element x in the x namespace. Instead, the rule will be dropped.

"Now"?  Did something change in the spec or in Firefox?

Comment 3

[Anne (:annevk)]

CSS 2.1 changed and http://dev.w3.org/csswg/css3-namespace/ changed accordingly. So not your fault :-)

Though it changed to match the behavior we've always had for counters, IIRC.

I think we should get this change into Firefox 3 since we're better off breaking compatibility sooner rather than later.

Attachment: patch

Make namespace identifiers case sensitive, and add tests for both that and for counter names being case sensitive.

Note that this fix essentially reverts bug 35813.

Simple fix to match a recent spec change.
