Status: VERIFIED INVALID

while developing an in-house document system i wanted to use xhtml strict for
xml compliance (using php). when embedding the content type of
"application/xhtml+xml" for the script (recommended from w3c xhtml media types)
stylesheets embedded with the <link> attribute do not get processed. the
workaround is to use "text/html" which is deprecated for xhtml.

Reproducible: Always

Steps to Reproduce:
may need to write a php script with the following line:
   header("Content-type: application/xhtml+xml");
use an external css document
   <link rel="stylesheet" media="screen" type="text/css" href="default.css" />

Actual Results:  
stylesheet does not get processed

Expected Results:  
stylesheet would have rendered the content in the document. this should be
corrected to maintain XHTML compliance. Although the workaround is acceptable at
the moment, the new mime type should be facilitated throughout mozilla

Comment 4

[Craig Sacco]

changing the line
   header("Content-type: application/xhtml+xml");
to
   header("Content-type: text/html");

is a workaround, but it is a deprecated mimetype for XHTML 1.0

Attachment: Here is proof of the fault in Mozilla

This file contains four files:
  default.css - the stylesheet document
  default.js - the javascript document (currently empty)
  testfile.xhtml - the xhtml script with application/xhtml+xml encoding
  testfile.html - the xhtml script with text/html encoding

It doesn't work in the .xhtml file because you have all the HTML selectors
written in uppercase.  That means they don't match the lowercase XHTML code.

Case matters.  See http://www.w3.org/TR/xhtml1/#C_13

thats correct - it is common in css to write the element name in upper case.

i tried to open these files in m$ie - the behaviour is much worse: it displays
the  xml tree!!! may contact micro$oft to improve their web browser
