title: <noscript> processing in XML documents
body: <p>Is there any difference in &lt;noscript> block processing for pages served with MIME-type <strong>text/html</strong> versus those served with MIME-type <strong>application/xhtml+xml</strong>?</p>
  
  <p>As far as I noticed &lt;noscript> block for <strong>text/html</strong> pages is not processed at all if JavaScript is disabled in browser. And what happens for <strong>application/xhtml+xml</strong> pages? I suspect that for such pages the  block is still analysed when JavaScript is disabled. But I failed to find any clarification of this issue.</p>
  
  <p>Could someone point me to appropriate W3C standard or provide any other clarification?</p>
  
  <p>PS. Situation of interest is visit counting services wich use &lt;noscript> block to track visitors with disabled JS. If elements (for example, zero-sized images) of &lt;noscript> blocks are downloaded in any case then such services should broke :(</p>
