76174 - [lang=en] selector fails to detect language specified via Content-Language HTTP headers

Status: RESOLVED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[Max Spicer]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)

According to the W3 HTML4.01 spec, an element should inherit language 
information from the HTTP Content-Language header 
(http://www.w3.org/TR/html401/struct/dirlang.html#h-8.1.2).  Therefore, a 
document served with these headers (say Content-Language : en) and a CSS2 rule 
such as [lang|=en] {color:red} should colour all elements' content red 
(assuming they don't set lang differently).  The HTML code that illustrates 
this is given at the bottom.  This document may need to be served (rather than 
just loaded as a file) for the Content-Language header to be inserted.  The URL 
I have given is served by a server configured to set the Content-Language 
header to en, so the META http-equiv tag is really unnecessary as well as by 
the http-equiv line in the source.

Reproducible: Always
Steps to Reproduce:
1. Go to the page referenced in the URL section.
2. Observe incorrect rendering.

Actual Results:  The first paragraph is not rendered in italics.  The second 
paragraph is.

Expected Results:  Both paragraphs should be rendered in italics.

  <BODY>

    <P>This paragraph should be in italics as it should inherit the language 
from the HTTP header.</P>

    <P lang="en">This paragraph has had the lang="en" attribute set 
explicitly.  This works, but shouldn't be neccessary.</P>

  </BODY>
</HTML>

invalid. [attr|=val] is defined to only work for specified attributes. What you
are talking about is :lang(), which we don't support but which has already got a
bug filed.
