Hello Nathan,

Not as I know!

But I will advise you to not include the stylesheet through Templavoila. 
I think it's better to use page.HeaderData beacuse it gives you better controll 
over the order of CSS-files and also other elements in the header. Also the 
use of page.includeCSS is possible to have the CSS-files in correct order. 
But it don't give the possibility to use conditional comments. But condition 
in TYPO3 gives you the possibility to serve different stylesheets to different 

Personaly I use something like this.
<---code snippets-->

page.headerData >
page.headerData = CARRAY
page.headerData {
    10 = TEXT
    10.value = <link href="some css" rel="stylesheet" type="text/css" />
    20 = TEXT
    20.value = <link href="some other css" rel="stylesheet" type="text/css" 
    30 = TEXT
    30.value (
         <!--[if IE 6]>
              <link> href="/myfile/path/ie6.css" rel="stylesheet" type="text/css" 
    40 = TEXT
    40.value = som javascript

<--- end code -->

If I'm going to change the CSS i only change the file referense. For instance 
if page 15 should have another colour theme than the other, but the HTML 
are identical i don't have to use another TV template. I only make an ext 
template on that page and using following TypoScript code.

page.headerData.20.value = <link href="my green css" rel="stylesheet" type="text/css" 

The possibility for different combinations and finetuning of the header are 
nearly endless. And it gives you perfect controll.
