Hi Mike, Thanks for the response.
<noscript> is illegal when placed in the <head> under XHTML v1 strict. Reports 3 errors: 1. <noscript> not allowed here. 2. document type doesn't allow <link> here. 3. end tag for "object" omitted - The killer failure as it refers to the </head> element. I tried a full URI too but it made no difference. While the same in the body reports one error, does not allow <link> here. Server-side languages cannot detect JavaScript on / off on initial page request.

The page has been speed tweaked as much as possible given IT / server restraints. Unfortunately the page now fails W3C formal grammar validation. Because the page as designed was a massive 1.4MB (previously 260 Kb - 330 Kb), JavaScript was used to fetch image upon demand rather than on-load or post-load. This greatly reduced the impact on the servers (critical) and improved the initial page load speed. Obviously a no JavaScript version was also required. The image references cannot be in the standard CSS as IE loaded all the images, used or not: .noJS .imgRef {background:url(...)} Will not work. All the image references were placed into a separate CSS noJS.css and the link in a <noscript> and this is where the validation breaks. Apparently <noscript> is illegal in the <head>, and a <noscript> containing a <link> is illegal in the body. <noscript> <link rel="stylesheet" href="/homepages/default/noJS.compressed.css" type="text/css" media="all" /> </noscript> I went for placing it in the body so the noscript is legal but the link reference is not. I can see no alternative, and wondered if any of the list members had a more valid solution?
