Hey all, I am used to refer to an external .css style-file with a link tag/rel attribute in a document's header as a majority of websites developers are ... ... like this: <link rel="stylesheet" type="text/css" href="root-tmp.css" title="style" /> Code (markup): ... and like this: <link href="style.css" rel="stylesheet" type="text/css"> <style type="text/css" media="style"><!-- @import url(style.css) style; --></style>; Code (markup): However, recently I've seen the following (also in the header, right after the XML specification: "<?xml version="1.1" encoding="windows-1250"?>") on some site for the first time ever: <?xml-stylesheet href="../style.css" type="text/css"?> Code (markup): Does this mean that it is possible to refer to a stylesheet file also with XML, and what's the difference between this in the above two ways of doing it!!? thanks, tayiper
