I actually didn't know it was in there. :-o It points back to HTML4 though  
which doesn't really give a solid definition. It's more an example of  
usage.

Say the document has the following snippet:

  <head>
   <style type="text/css">
    p { background:lime }
   </style>
  </head>

... it should be clear that Link enters the (CSS) cascade before that. So  
that if you attach a style sheet using Link containg `p { background:red  
}`, <p> elements will have a green background.

See also the last paragraph of  
http://www.w3.org/TR/1999/REC-html401-19991224/present/styles.html#h-14.6  
for another way of saying it. I think this should be in the specification  
that defines Link rather than in every specification that defines a way to  
attach style sheets in documents like <svg:style>, <html:style>,  
<html:link> and <?xml-stylesheet?>...
