           Summary: handle gracefully missing title element in alternate
                    stylesheets
           Product: konqueror
           Version: 3.2.2
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: konq-bugs kde org
        ReportedBy: asp16 alu ua es


Version:           3.2.2 (using KDE 3.2.3,  (testing/unstable))
Compiler:          gcc version 3.3.4 (Debian 1:3.3.4-4)
OS:                Linux (i686) release 2.6.7-1-686

[This is Debian Bug#231179, reported by Ambrose Li <ambrose.li cccgt org>  You can \
read the full log at <http://bugs.debian.org/231179>.]

This is somehow related to KDE Bug#54335, which I understand, but different. Taking \
the sample page by Jon Dowland (http://toast.debian.net/~jmtd/konq/index.html), which \
now works, we have:

    <link   rel="alternate stylesheet" href="red.css"  type="text/css" title="Red"  \
/>  <link   rel="stylesheet"           href="blue.css" type="text/css" title="Blue" \
/>

That works as intended (blue background). Problem arises when *both* of the two \
following conditions are met:

    1. "alternate stylesheet" lacks a "title" element.
    2. "alternate stylesheet" appears *after* "stylesheet".

In that case, red background is obtained. As I wrote in the Debian bug report:

  the real problem here is that the alternate stylesheet test.css does
  not have a title element which is, as per the relevant W3C specification
  (http://www.w3.org/TR/REC-html40/present/styles.html#h-14.3.2) and AIUI,
  not a valid scenario for an alternate stylesheet:

      Specify that the style sheet is persistent, preferred, or alternate:

        - To make a style sheet persistent, set the rel attribute to
          "stylesheet" and don't set the title attribute.

        - To make a style sheet preferred, set the rel attribute to
          "stylesheet" and name the style sheet with the title
          attribute.

        - To specify an alternate style sheet, set the rel attribute to
          "alternate stylesheet" and name the style sheet with the title
          attribute.

  the user fix for this is to specify a title="foo" element in the
  alternate stylesheet link tag.

  however, as seems reasonable to handle the missing title element
  gracefully, and other browsers certainly do so, I'm forwarding this to
  upstream developers to see what they think.

thanks.
