Details 
I was pleased to find that Mozilla will read an xml file and an associate XSLT
stylesheet and render the resulting HTML output.  Nifty!  Unfortunately, it
appears that if the generated output includes stylesheet <link> elements in the
<head> element, these are ignored.

In other words:  The HTML generated by my XSLT stylesheet includes:

  <link rel="stylesheet" type="text/css" href="standard.css">

If I generate the html manually using xsltproc and point Mozilla at the
resulting html file, the CSS stylesheet works as expected.  On the other hand,
if I point mozilla at the XML file (with an embedded xml-stylesheet element),
the XSLT transform works correctly, but the CSS stylesheet is never consulted.
IIRC, this is something glazou has a fix for. But I can't find the bug.
dumb me.
Whiteboard: [dupeme]
This should be being covered under bug 96647. I think its actually a dup of  bug
53030, but I'm not totally sure so aren't going to mark it as such myself.
non of the above.
It is indeed bug 34849, which I found by looking at the bugs above, so thanx
for the links.
Leaving up for peterv or glazou to make up if this depends or dupes.
(I tend to depend)
I don't think it's that one either. This is a linked stylesheet which should 
work since the fix of bug 7515!

lars: could you attach the xml-page and the xslt-stylesheet that you get this 
error in. Please read the guidelines in http://www.mozilla.org/projects/xslt 
before attaching

    
    

    
  


  

    
    

    
  


  

    
    

    
  
I've attached a trivial xml document, the corresponding xslt stylesheet, and the
css stylesheet.  Note that I am opening these on disks, not from a server.


    
    

    
  
This is due to the stylesheet having capital tag names, BODY and P, but xhtml
(which is our output) being lower case.
Confirming, though I'm not sure if we gonna fix this

Interesting.  I hadn't considered the fact the the css selectors were case
sensitive, but of course that makes perfect sense when the target document is XHTML.

Not really a bug, I guess, although it might be worth noting prominently
somewhere...


    
    

    
  
Excerpt from CSS 2 spec section 4.1.3 :

  All CSS style sheets are case-insensitive, except for parts that are not
  under the control of CSS. For example, the case-sensitivity of values of
  the HTML attributes "id" and "class", of font names, and of URIs lies
  outside the scope of this specification. Note in particular that element
  names are case-insensitive in HTML, but case-sensitive in XML.

Excerpt from section 5.1 :

  The case-sensitivity of document language element names in selectors
  depends on the document language. For example, in HTML, element names are
  case-insensitive, but in XML they are case-sensitive.

Excerpt from section 5.8.1 :

  The case-sensitivity of attribute names and values in selectors
  depends on the document language.



    
    

    
  
glazou: how does layout know that some content is html and should be styled case-insensitive? Does it check the document-object or the elements? What does it check on these objects? Would it be possible for us to fool style that the xhtml document is a html document?

Since transformiix really should output html and not xhtml it would be good if we could make the xhtml behave as much as possible as html.

The HTML content sink asks the document object for a CSSLoader.  If you look at
GetCSSLoader() on the various documents (nsHTMLDocument, nsXMLDocument being the
two you care about here) you'll see that the document sets the case-sensitivity
of the CSSLoader.

I'm not sure how you can go about fooling the document into mis-setting the
case-sensitivity of the CSSLoader.
