Clarification of the previous - a network capture of an entire HTTP header
as emitted by Amaya shows that it does not emit a Referer: HTTP header with
a GET request:-

The check/referer URL is of course the one in the mark-up offered on the
validator page after a successful validation; and referse to some executable
that parses the GET header for the Referer: line.
 
It is a separate issue that Amaya and the validator.w3.org parser produce
slightly different reports given the same input (e.g. Amaya notes that
<a><applet/></a> is not valid XHTML1.0 Transitional, but validator.w3.org
accepts it).

Subject: One problem carried over, and a new one (Amaya 8.1a)
 
Using Amaya 8.1a on Win2k Advanced Server 
1) Newly spotted problem - empty referrer 
Following a link of the form http://validator.w3.org/check/referer
<http://validator.w3.org/check/referer>  leads to the page
http://validator.w3.org/check?uri= <http://validator.w3.org/check?uri=>  
2) Problem carried forwards from 7.x - using the following works if the page
loaded and the css file are in the same directory on the local host
<style type="text/css" media="screen">@import url( site.css );</style> 
and such CSS as Amaya supports (i.e. we expect positioning not to work yet)
is carried out; but when the files are placed on a web-server, it does not
(though Mozilla 1.4 and IE6 resolve it); and the CSS files are fetched
(according to the status line)
